0 W When each of the port C pins, PC1 and PC0, functions as
an general I/O port, setting a PCRC bit to 1 makes the
0 W
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
Initial
Value R/W Description
 
Reserved
0 R/W These bits store output data for port C pins.
0 R/W If PDRC is read while PCRC bits are set to 1, the value
stored in PDRC is read. If PDRC is read while PCRC bits
are cleared to 0, the pin states are read regardless of the
value stored in PDRC.
