Note: Unused bits have to be set to logical â0â.
Each PCR register is accessible via two channel addresses.
Each of the above bits is assigned to the Universal Port pin (P0â¦P7) with the same
number(e.g. PCRA.0 to pin PA0). If bit PCRn (n = 0â¦7) is set to
0â¦pin Pn is defined as output.
1â¦pin Pn is defined as input.
Note: After RESET, all pins of the Universal Port are defined as inputs.
