Freescale Semiconductor
When bit DDRCx is a logic 1, reading address $0002 reads the PTCx
data latch. When bit 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.
the operation of the port C pins.

1. X = don’t care
2. Hi-Z = high impedance on PTC0 and a pull-down R
3. Writing affects data register, but does not affect input.
