23.3.2 Port C Data Register (PCDR)
PCDR is a 16-bit readable/writable register that stores data for pins PTC15 to PTC0. PCDR is
initialized to H'0000 by a power-on reset, but it retains its previous value by a manual reset, in
standby mode, or in sleep mode.

R/W Bits PC15DT to PC0DT correspond to pins PTC15 to
R/W ^{PTC0. When the pin function is general output port,}
the value of the corresponding bit in PCDR is returned
R/W _{directly by reading the port. When the function is}
R/W ^{general input port, the corresponding pin level is read}
by reading the port. Table 23.3 shows the function of
R/W _PCDR.
