P55/WKP5/ADTRG Pin Function Switch
Selects whether pin P55/WKP5/ADTRG is used as P55
or as WKP5/ADTRG.
0: General I/O port
1: WKP5/ADTRG input pin
Reserved
These bits are always read as 0.
Description
When each of the port 5 pins, P57 to P55, functions as an
general I/O port, setting a PCR5 bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
