+
+/**
+ * A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
+ * The servos are pulsed in the background using the value most recently written using the write() method
+ *
+ * Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
+ * Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
+ *
+ * The methods are:
+ *
+ * Servo - Class for manipulating servo motors connected to Arduino pins.
+ *
+ * attach(pin) - Attach a servo motor to an i/o pin.
+ * attach(pin, min, max) - Attach to a pin, setting min and max values in microseconds
+ * Default min is 544, max is 2400
+ *
+ * write() - Set the servo angle in degrees. (Invalid angles —over MIN_PULSE_WIDTH— are treated as µs.)
+ * writeMicroseconds() - Set the servo pulse width in microseconds.
+ * move(pin, angle) - Sequence of attach(pin), write(angle), safe_delay(servo_delay[servoIndex]).
+ * With DEACTIVATE_SERVOS_AFTER_MOVE it detaches after servo_delay[servoIndex].
+ * read() - Get the last-written servo pulse width as an angle between 0 and 180.
+ * readMicroseconds() - Get the last-written servo pulse width in microseconds.
+ * attached() - Return true if a servo is attached.
+ * detach() - Stop an attached servo from pulsing its i/o pin.

+/* EEPROM emulation over flash with reduced wear
+ *
+ * We will use 2 contiguous groups of pages as main and alternate.
+ * We want an structure that allows to read as fast as possible,
+ * without the need of scanning the whole FLASH memory.
+ *
+ * FLASH bits default erased state is 1, and can be set to 0
+ * on a per bit basis. To reset them to 1, a full page erase
+ * is needed.
+ *
+ * Values are stored as differences that should be applied to a
+ * completely erased EEPROM (filled with 0xFFs). We just encode
+ * the starting address of the values to change, the length of
+ * the block of new values, and the values themselves. All diffs
+ * are accumulated into a RAM buffer, compacted into the least
+ * amount of non overlapping diffs possible and sorted by starting
+ * address before being saved into the next available page of FLASH
+ * of the current group.
+ * Once the current group is completely full, we compact it and save
+ * it into the other group, then erase the current group and switch
+ * to that new group and set it as current.
+ *
+ * The FLASH endurance is about 1/10 ... 1/100 of an EEPROM
+ * endurance, but EEPROM endurance is specified per byte, not
+ * per page. We can't emulate EE endurance with FLASH for all
+ * bytes, but we can emulate endurance for a given percent of
+ * bytes.

+ * The PWM module is only used to generate interrupts at specified times. It
+ * is NOT used to directly toggle pins. The ISR writes to the pin assigned to
+ * that interrupt.
+ *
+ * All PWMs use the same repetition rate. The G2 needs about 10KHz min in order to
+ * not have obvious ripple on the Vref signals.
+ *
+ * The data structures are setup to minimize the computation done by the ISR which
+ * minimizes ISR execution time. Execution times are 0.8 to 1.1 microseconds.
+ *
+ * FIve PWM interrupt sources are used. Channel 0 sets the base period. All Vref
+ * signals are set active when this counter overflows and resets to zero. The compare
+ * values in channels 1-4 are set to give the desired duty cycle for that Vref pin.
+ * When counter 0 matches the compare value then that channel generates an interrupt.
+ * The ISR checks the source of the interrupt and sets the corresponding pin inactive.
+ *
+ * Some jitter in the Vref signal is OK so the interrupt priority is left at its default value.

+ * analogRead
+ * analogWrite
+ * digitalWrite
+ * pinMode
+ *
+ * The FASTIO routines do not touch the g_pinStatus[pin] array.
+ *
+ * The net result is that both the g_pinStatus[pin] array and the PIO_OSR register
+ * needs to be looked at when determining if a pin is an input or an output.
+ *
+ * b) Due has only pins 6, 7, 8 & 9 enabled for PWMs. FYI - they run at 1KHz
+ *
+ * c) NUM_DIGITAL_PINS does not include the analog pins

+ *
+ * \section sysclk_quickstart_basic Basic usage of the System Clock Management service
+ * This section will present a basic use case for the System Clock Management service.
+ * This use case will configure the main system clock to 84MHz, using an internal PLL
+ * module to multiply the frequency of a crystal attached to the microcontroller.
+ *
+ * \subsection sysclk_quickstart_use_case_1_prereq Prerequisites
+ * - None
+ *
+ * \subsection sysclk_quickstart_use_case_1_setup_steps Initialization code
+ * Add to the application initialization code:
+ * \code
+ sysclk_init();
+\endcode
+ *
+ * \subsection sysclk_quickstart_use_case_1_setup_steps_workflow Workflow
+ * -# Configure the system clocks according to the settings in conf_clock.h:
+ * \code sysclk_init(); \endcode
+ *
+ * \subsection sysclk_quickstart_use_case_1_example_code Example code
+ * Add or uncomment the following in your conf_clock.h header file, commenting out all other
+ * definitions of the same symbol(s):
+ * \code
+ #define CONFIG_SYSCLK_SOURCE SYSCLK_SRC_PLLACK
+
+ // Fpll0 = (Fclk * PLL_mul) / PLL_div
+ #define CONFIG_PLL0_SOURCE PLL_SRC_MAINCK_XTAL
+ #define CONFIG_PLL0_MUL (84000000UL / BOARD_FREQ_MAINCK_XTAL)
+ #define CONFIG_PLL0_DIV 1
+
+ // Fbus = Fsys / BUS_div
+ #define CONFIG_SYSCLK_PRES SYSCLK_PRES_1
+\endcode
+ *
+ * \subsection sysclk_quickstart_use_case_1_example_workflow Workflow
+ * -# Configure the main system clock to use the output of the PLL module as its source:
+ * \code #define CONFIG_SYSCLK_SOURCE SYSCLK_SRC_PLLACK \endcode
+ * -# Configure the PLL module to use the fast external fast crystal oscillator as its source:
+ * \code #define CONFIG_PLL0_SOURCE PLL_SRC_MAINCK_XTAL \endcode
+ * -# Configure the PLL module to multiply the external fast crystal oscillator frequency up to 84MHz:
+ * \code
+ #define CONFIG_PLL0_MUL (84000000UL / BOARD_FREQ_MAINCK_XTAL)
+ #define CONFIG_PLL0_DIV 1
+\endcode
+ * \note For user boards, \c BOARD_FREQ_MAINCK_XTAL should be defined in the board \c conf_board.h configuration
+ * file as the frequency of the fast crystal attached to the microcontroller.
+ * -# Configure the main clock to run at the full 84MHz, disable scaling of the main system clock speed:
+ * \code
+ #define CONFIG_SYSCLK_PRES SYSCLK_PRES_1

+ * The following procedure must be executed to setup the project correctly:
+ * - Specify the clock configuration:
+ * - XMEGA USB devices need 48MHz clock input.\n
+ * XMEGA USB devices need CPU frequency higher than 12MHz.\n
+ * You can use either an internal RC48MHz auto calibrated by Start of Frames
+ * or an external OSC.
+ * - UC3 and SAM3/4 devices without USB high speed support need 48MHz clock input.\n
+ * You must use a PLL and an external OSC.
+ * - UC3 and SAM3/4 devices with USB high speed support need 12MHz clock input.\n
+ * You must use an external OSC.
+ * - UC3 devices with USBC hardware need CPU frequency higher than 25MHz.
+ * - SAMD devices without USB high speed support need 48MHz clock input.\n
+ * You should use DFLL with USBCRM.
+ * - In conf_board.h, the define CONF_BOARD_USB_PORT must be added to enable USB lines.
+ * (Not mandatory for all boards)
+ * - Enable interrupts
+ * - Initialize the clock service
+ *
+ * The usage of \ref sleepmgr_group sleepmgr service is optional, but recommended to reduce power
+ * consumption:
+ * - Initialize the sleep manager service
+ * - Activate sleep mode when the application is in IDLE state
+ *
+ * \subpage udc_conf_clock.

+ * \section udi_cdc_basic_use_case Basic use case
+ * In this basic use case, the "USB CDC (Single Interface Device)" module is used
+ * with only one communication port.
+ * The "USB CDC (Composite Device)" module usage is described in \ref udi_cdc_use_cases
+ * "Advanced use cases".

+ *
+ * This is the quick start guide for the \ref udi_msc_group
+ * "USB device interface MSC module (UDI MSC)" with step-by-step instructions on
+ * how to configure and use the modules in a selection of use cases.
+ *
+ * The use cases contain several code fragments. The code fragments in the
+ * steps for setup can be copied into a custom initialization function, while
+ * the steps for usage can be copied into, e.g., the main application function.
+ *
+ * \section udi_msc_basic_use_case Basic use case
+ * In this basic use case, the "USB MSC (Single Interface Device)" module is used.
+ * The "USB MSC (Composite Device)" module usage is described in \ref udi_msc_use_cases
+ * "Advanced use cases".

+ *
+ * \subsection udi_msc_basic_use_case_setup_flow Workflow
+ * -# Ensure that conf_usb.h is available and contains the following configuration,
+ * which is the USB device MSC configuration:
+ * - \code #define USB_DEVICE_SERIAL_NAME "12...EF" // Disk SN for MSC \endcode
+ * \note The USB serial number is mandatory when a MSC interface is used.
+ * - \code //! Vendor name and Product version of MSC interface
+ #define UDI_MSC_GLOBAL_VENDOR_ID \
+ 'A', 'T', 'M', 'E', 'L', ' ', ' ', ' '
+ #define UDI_MSC_GLOBAL_PRODUCT_VERSION \
+ '1', '.', '0', '0' \endcode
+ * \note The USB MSC interface requires a vendor ID (8 ASCII characters)
+ * and a product version (4 ASCII characters).
+ * - \code #define UDI_MSC_ENABLE_EXT() my_callback_msc_enable()
+ extern bool my_callback_msc_enable(void); \endcode
+ * \note After the device enumeration (detecting and identifying USB devices),
+ * the USB host starts the device configuration. When the USB MSC interface
+ * from the device is accepted by the host, the USB host enables this interface and the
+ * UDI_MSC_ENABLE_EXT() callback function is called and return true.
+ * Thus, when this event is received, the tasks which call
+ * udi_msc_process_trans() must be enabled.
+ * - \code #define UDI_MSC_DISABLE_EXT() my_callback_msc_disable()
+ extern void my_callback_msc_disable(void); \endcode
+ * \note When the USB device is unplugged or is reset by the USB host, the USB
+ * interface is disabled and the UDI_MSC_DISABLE_EXT() callback function
+ * is called. Thus, it is recommended to disable the task which is called udi_msc_process_trans().
+ * -# The MSC is automatically linked with memory control access component
+ * which provides the memories interfaces. However, the memory data transfers
+ * must be done outside USB interrupt routine. This is done in the MSC process
+ * ("udi_msc_process_trans()") called by main loop:
+ * - \code * void task(void) {
+ udi_msc_process_trans();
+ } \endcode
+ * -# The MSC speed depends on task periodicity. To get the best speed
+ * the notification callback "UDI_MSC_NOTIFY_TRANS_EXT" can be used to wakeup
+ * this task (Example, through a mutex):
+ * - \code #define UDI_MSC_NOTIFY_TRANS_EXT() msc_notify_trans()
+ void msc_notify_trans(void) {
+ wakeup_my_task();
+ } \endcode
+ *
+ * \section udi_msc_use_cases Advanced use cases
+ * For more advanced use of the UDI MSC module, see the following use cases:
+ * - \subpage udi_msc_use_case_composite

+ *
+ * Static declarations defined in conf_usb.h:
+ * - UDC_VBUS_EVENT(bool b_present)
+ * To signal Vbus level change
+ * - UDC_SUSPEND_EVENT()
+ * Called when USB bus enter in suspend mode
+ * - UDC_RESUME_EVENT()
+ * Called when USB bus is wakeup
+ * - UDC_SOF_EVENT()
+ * Called for each received SOF, Note: Each 1ms in HS/FS mode only.
+ *
+ * Dynamic callbacks, called "endpoint job" , are registered
+ * in udd_ep_job_t structure via the following functions:
+ * - udd_ep_run()
+ * To call it when a transfer is finish
+ * - udd_ep_wait_stall_clear()
+ * To call it when a endpoint halt is disabled
+ *
+ * \section Power mode management
+ * The Sleep modes authorized :
