/**

|
* @defgroup AT91SAM7X_PAL I/O Ports Support
|
|
* @brief I/O Ports peripherals support.
|
|
* @details This module supports the AT91SAM7X PIO controller. The controller
|
|
* supports the following features (see @ref PAL):
|
|
* - 32 bits wide ports.
|
|
* - Atomic set/reset functions.
|
|
* - 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_OUTPUT_PUSHPULL.
|
|
* - @p PAL_MODE_OUTPUT_OPENDRAIN.
|
|
* .
|
|
* Any attempt to setup an invalid mode is ignored.
|
|
*
|
|
* <h2>Suboptimal Behavior</h2>
|
|
* Some PIO features are less than optimal:
|
|
* - Pad/port toggling operations are not atomic.
|
|
* - Pad/group mode setup is not atomic.
