- * @details MSP430 port details. This section how the ChibiOS/RT features are
- * implemented on this architecture.
- *
- * @section MSP430_STATES Mapping of the System States in the MSP430 port
- * The ChibiOS/RT logical @ref system_states are mapped as follow in the MSP430
- * 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>. Not yet implemented.
- * - <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>. The MSP430 has several non
- * maskable interrupt sources that can be associated to this state.
- * - <b>Halted</b>. Implemented as an infinite loop with interrupts disabled.
- * .
- * @section MSP430_NOTES The MSP430 port notes
- * - The MSP430 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/MSP430/chcore.h</b>.
- * - The state of the hardware multiplier is not saved in the thread context,
- * make sure to use it in <b>Suspended</b> state (interrupts masked).
- * - The port code does not define the switch to a low power mode for the
- * idle thread because the MSP430 has several low power modes. You can
- * select the proper low power mode for you application by defining the
- * macro @p port_wait_for_interrupt().

- * settings that 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>

- * - 8 bits wide ports.
- * - Atomic set/reset/toggle functions because special MSP430 instruction set.

- * <h2>Suboptimal Behavior</h2>
- * Some MSP430 I/O ports features are less than optimal:
- * - Bus/group writing is not atomic.
- * - Pad/group mode setup is not atomic.
