+ * @defgroup MSP430 MSP430
+ * @details MSP430 port for the GCC/IAR compiler.
+ *
+ * @section MSP430_INTRO Introduction
+ * This port supports all the cores implementing the MSP430 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 disabled. 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 configuration options.
+ * - 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().
+ * .

+/**
+ * @defgroup MSP430_CONF Configuration Options
+ * @details MSP430 Configuration Options. The MSP430 port allows some
+ * architecture-specific configurations settings that can be overridden
+ * by redefining them in @p chconf.h. Usually there is no need to change
+ * the default values.
+ * - @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.
+ * - @p IDLE_THREAD_STACK_SIZE, stack area size to be assigned to the IDLE
+ *   thread. Usually there is no need to change this value unless inserting
+ *   code in the IDLE thread hook macro.
