0: When the corresponding pin is designated as a
general I/O port, the pin functions as an input
port.
1: When the corresponding pin is designated as a
general I/O port, the pin functions as an output
port.
PCR6 is a register that selects inputs/outputs in bit
units for pins to be used as general I/O ports of port
6.
R/W
• PCR67 bit to PCR60 bit (port 67 to 60 control)
When the corresponding pin is designated in PMR6 as a general I/O pin, setting a PCR6 bit to
1 makes the corresponding pin an output port, while clearing the bit to 0 makes the pin an
input port.
