-/**

- * @defgroup AVR MegaAVR

- * @details AVR port details. This section how the ChibiOS/RT features are

- * implemented on this architecture.

- *

- * @section AVR_STATES Mapping of the System States in the AVR port

- * The ChibiOS/RT logical @ref system_states are mapped as follow in the AVR

- * port:

- * - <b>Init</b>. This state is represented by the startup code and the

- *   initialization code before @p chSysInit() is executed. It has not a

- *   special hardware state associated.

- * - <b>Normal</b>. This is the state the system has after executing

- *   @p chSysInit(). Interrupts are enabled.

- * - <b>Suspended</b>. Interrupts are disabled.

- * - <b>Disabled</b>. Interrupts are enabled. This state is equivalent to the

- *   Suspended state because there are no fast interrupts in this architecture.

- * - <b>Sleep</b>. This state is entered with the execution of the specific

- *   instruction @p <b>sleep</b>.

- * - <b>S-Locked</b>. Interrupts are disabled.

- * - <b>I-Locked</b>. This state is equivalent to the SRI state, the

- *   @p chSysLockI() and @p chSysUnlockI() APIs do nothing (still use them in

- *   order to formally change state because this may change).

- * - <b>Serving Regular Interrupt</b>. Normal interrupt service code.

- * - <b>Serving Fast Interrupt</b>. Not present in this architecture.

- * - <b>Serving Non-Maskable Interrupt</b>. Not present in this architecture.

- * - <b>Halted</b>. Implemented as an infinite loop with interrupts disabled.

- * .

- * @section AVR_NOTES The AVR port notes

- * - The AVR does not have a dedicated interrupt stack, make sure to reserve

- *   enough stack space for interrupts in each thread stack. This can be done

- *   by modifying the @p INT_REQUIRED_STACK macro into

- *   <b>./ports/AVR/chcore.h</b>.

- * .

- * @ingroup Ports

- * settingsthat can be specified externally, as example on the compiler

- * command line:

- * - @p INT_REQUIRED_STACK, this value represent the amount of stack space

- *   used by the interrupt handlers.<br>

- *   The default for this value is @p 32, this space is allocated for each

- *   thread so be careful in order to not waste precious RAM space.<br>
