- * @defgroup STM8_RAISONANCE STM8

- * @details STM8 port for the Raisonance C compiler.

- *

- * @section STM8_RAISONANCE_INTRO Introduction

- * This port supports all STM8 8 bits MCUs.

- *

- * @section STM8_RAISONANCE_STATES Mapping of the System States in the STM8 port

- * The ChibiOS/RT logical @ref system_states are mapped as follow in the STM8

- * 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>. Implemented with "wait" instruction insertion in the idle

- *   loop.

- * - <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 STM8 ha non

- *   maskable interrupt sources that can be associated to this state.

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

- * .

- * @section STM8_RAISONANCE_NOTES The STM8 port notes

- * - The STM8 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>./os/ports/RC/STM8/chcore.h</b>.

- * - The kernel currently supports only the small memory model so the

- *   kernel files should be loaded in the first 64K. Note that this is not

- *   a problem because upper addresses can be used by the user code, the

- *   kernel can context switch code running there.

- * - The configuration option @p CH_CFG_OPTIMIZE_SPEED is not currently supported

- *   because the missing support of the @p inline "C" keyword in the

- *   compiler.

- * .

-/**

- * @defgroup STM8_RAISONANCE_CONF Configuration Options

- * @details STM8 Configuration Options. The STM8 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 48, this space is allocated for each

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