 * @defgroup STM32 STM32 Support
 * @brief STM32 specific support.
 * @details The STM32 support includes:
 * - I/O ports driver.
 * - Buffered, interrupt driven, serial driver.
 * - Interrupt driver CAN driver.
 * - DMA capable, high performance, ADC driver.
 * - DMA capable, high performance, SPI driver.
 * - PWM driver.
 * - A demo supporting the kernel test suite.
 * - A demo that demonstrate the FatFs use with the MMC driver.

/**
 * @defgroup STM32_PAL STM32 I/O Ports Support
 * @brief I/O Ports peripherals support.
 * @details This module supports the STM3 GPIO controller. The controller
 * supports the following features (see @ref PAL):
 * - 16 bits wide ports.
 * - Atomic set/reset functions.
 * - Atomic set+reset function (atomic bus operations).
 * - Output latched regardless of the pad setting.
 * - Direct read of input pads regardless of the pad setting.
 * .
 * <h2>Supported Setup Modes</h2>
 * - @p PAL_MODE_RESET.
 * - @p PAL_MODE_UNCONNECTED.
 * - @p PAL_MODE_INPUT.
 * - @p PAL_MODE_INPUT_PULLUP.
 * - @p PAL_MODE_INPUT_PULLDOWN.
 * - @p PAL_MODE_INPUT_ANALOG.
 * - @p PAL_MODE_OUTPUT_PUSHPULL.
 * - @p PAL_MODE_OUTPUT_OPENDRAIN.
 * .
 * Any attempt to setup an invalid mode is ignored.
 *
 * <h2>Suboptimal Behavior</h2>
 * Some GPIO features are less than optimal:
 * - Pad/port toggling operations are not atomic.
 * - Pad/group mode setup is not atomic.
 * - Writing on pads/groups/ports programmed as input with pull-up/down
 *   resistor can change the resistor setting because the output latch is
 *   used for resistor selection.
