AF[7:0]—Port Alternate Function enabled
0 = The port pin is in normal mode and the DDx bit in the Port A-H Data Direction sub-
register determines the direction of the pin.
1 = The alternate function is selected. Port pin operation is controlled by the alternate
function.
Port A-H Output Control Sub-Registers
The Port A-H Output Control sub-register (Table 17) is accessed through the Port A-H
Control register by writing
Port A-H 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 disables the drains if set
to 1.
0 = The drains are enabled for any output mode.
1 = The drain of the associated pin is disabled (open-drain mode).
