When DDRCx is a logic 1, reading address $0002 reads the PTCx data
latch. When DDRCx is a logic 0, reading address $0002 reads the
voltage level on the pin. The data latch can always be written, regardless
of the state of its data direction bit.

Notes:
1. X = don’t care; except PTC2.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect input.
