function associated with each port pin.
AF[7:0]—Port Alternate Function enabled
0 = The port pin is in normal mode and the DDx bit in the Port A–C Data Direction sub-
register determines the direction of the pin.
1 = The alternate function selected through Alternate Function Set sub-registers is
enabled. Port pin operation is controlled by the alternate function.
Port A–C Output Control Sub-Registers
The Port A–C Output Control sub-register
Control register by writing
Port A–C Output Control sub-registers to 1 configures the specified port pins for open-
drain operation. These sub-registers 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.
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.
