The Port A–H Output Control sub-register
Port A–H Control register by writing
bits in the 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, alter-
nate functions 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).
