/**
* @defgroup STM32F103 STM32F103 Support
* @brief STM32F103 specific support.
* @details The STM32F103 support includes:
* - I/O ports driver.
* - Buffered, interrupt driven, serial driver.
* - A demo supporting the kernel test suite.

/**
* @defgroup STM32F103_PAL I/O Ports Support
* @brief I/O Ports peripherals support.
* @details This module supports the STM32F103 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_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.
* .
