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 (Table 22) is accessed through the Port A–C
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 func-
tions 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 func-
tion).
1 = The drain of the associated pin is disabled (open-drain mode).
Table 21. Port A–C Alternate Function Sub-Registers (PxAF)
Table 22. Port A–C Output Control Sub-Registers (PxOC)
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.
