Section 18 I/O Ports
18.3.2
Port C data register (PCDR) is an 8-bit read/write register that stores data for pins PTC7 to PTC0.
PC7DT to PC0DT bit corresponds to PTC7 to PTC0 pin. When the pin function is general output
port, if the port is read, the value of the corresponding PCDR bit is returned directly. When the
function is general input port, if the port is read, the corresponding pin level is read. Table 18.3
shows the function of PCDR.
PCDR is initialized to H'00 by a power-on reset. It retains its previous value in standby mode and
sleep mode, and in a manual reset.
