AF[7:0]—Port Alternate function enabled
0 = The port pin is in NORMAL mode and the DDx bit in the Port A–D data direction
subregister determines the direction of the pin.
1 = The Alternate function selected through Alternate function set subregisters is enabled.
Port pin operation is controlled by the Alternate function.
Port A–D Output Control Subregisters
The Port A–D output control subregister is accessed through the Port A–D control register
by writing
A–D output control subregisters to 1, configures the specified port pins for open-drain
operation. These subregisters affect the pins directly and, as a result, Alternate functions
are also affected.
POC[7:0]—Port output control
These bits function independently of the Alternate function bit and always disable the
drains, if set to 1.
0 = The drains are enabled for any OUTPUT mode (unless overridden by the Alternate
function).
1 = The drain of the associated pin is disabled (OPEN-DRAIN mode).
Do not enable Alternate functions for GPIO port pins for which there is no
associated Alternate function. Failure to follow this guideline can result in
unpredictable operation.
