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).
Access
This register can be read/written in 8-bit and 1-bit units.
Address
see
“Port Group Configuration“ on page 56
Initial Value
00
H
This register is initialized by any reset.
(4)
PODCn - Port open drain control register
The PODCn register selects the output buffer function as push-pull or open-
drain emulation.
Access
This register can be read/written in 8-bit and 1-bit units.
Address
see
“Port Group Configuration“ on page 56
Initial Value
00
H
. This register is cleared by any reset.
If open drain emulation is enabled the output function of concerned pin is
automatically enabled as well, independently of the PMn.PMnm setting.
