PILCn - Port input level control register
The 8-bit PILCn register selects between different input characteristics for
Schmitt Trigger (PICCn.PICCnm = 1) and non-Schmitt Trigger
(PICCn.PICCnm = 0).
This register can be read/written in 8-bit and 1-bit units.
see “Port Group Configuration“ on page 56
00
This register is initialized by any reset.
PILCn register contents
PODCn - Port open drain control register
The PODCn register selects the output buffer function as push-pull or open-
drain emulation.
This register can be read/written in 8-bit and 1-bit units.
see “Port Group Configuration“ on page 56

PODCn register contents
If open drain emulation is enabled the output function of concerned pin is
automatically enabled as well, independently of the PMn.PMnm setting.
