+ * The AVR PAL driver implementation fully supports the following hardware

+ * - 8 bits wide ports.
+ * - Atomic set/reset functions.
+ * - Output latched regardless of the pad setting.
+ * - Direct read of input pads regardless of the pad setting.
+ * .
+ * @section avr_pal_3 Supported PAL setup modes
+ * The AVR PAL driver supports the following I/O modes:
+ * - @p PAL_MODE_RESET.
+ * - @p PAL_MODE_UNCONNECTED.
+ * - @p PAL_MODE_INPUT.
+ * - @p PAL_MODE_INPUT_PULLUP.
+ * - @p PAL_MODE_INPUT_ANALOG.
+ * - @p PAL_MODE_OUTPUT_PUSHPULL.
+ * .
+ * Any attempt to setup an invalid mode is ignored.
+ *
+ * @section avr_pal_4 Suboptimal behavior
+ * The AVR PORT is less than optimal in several areas, the limitations
+ * should be taken in account while using the PAL driver:
+ * - Pad/port toggling operations are not atomic.
+ * - Pad/group mode setup is not atomic.
+ * - Group set+reset function is not atomic.
+ * - Writing on pads/groups/ports programmed as input with pull-up
+ * resistor changes the resistor setting because the output latch is
+ * used for resistor selection.
+ * - The PORT registers layout on some devices is not regular (it does
+ * not have contiguous PIN, DDR, PORT registers in this order), such
+ * ports cannot be accessed using the PAL driver. For example, PORT F
+ * on ATmega128. Verify the user manual of your device.

+ *
+ * The file is the unique include file that the application programmer
+ * is using in the C source code, usually in main.c. This file contains:
+ * - Configuration section that allows to select:
+ * - The device used in the target application
+ * - To use or not the peripheral’s drivers in application code(i.e.
+ * code will be based on direct access to peripheral’s registers
+ * rather than drivers API), this option is controlled by
+ * "#define USE_STDPERIPH_DRIVER"
+ * - To change few application-specific parameters such as the HSE
+ * crystal frequency
+ * - Data structures and the address mapping for all peripherals
+ * - Peripheral's registers declarations and bits definition
+ * - Macros to access peripheral’s registers hardware
