|
|
* @brief I/O Ports peripherals support.
|
||
|
|
* @details This module supports the LPC13xx GPIO controller. The controller
|
||
|
|
* supports the following features (see @ref PAL):
|
||
|
|
* - 12 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_OUTPUT_PUSHPULL.
|
||
|
|
* .
|
||
|
|
* 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.
|
||
|
|
* - Pull-up and Pull-down resistors cannot be programmed through the PAL
|
||
|
|
* driver and must be programmed separately.
|
||
|
|
* - Reading of the output latch for pads programmed as input is not possible,
|
||
|
|
* the input pin value is returned instead.
