Section 22 I/O Ports
22.3.2
PCDRH and PCDRL are 16-bit readable/writable registers that store port C data. Bits PC21DR to
PC0DR correspond to pins PC21 to PC0, respectively.
If a pin is set to the general output function, the pin will output the value written to the
corresponding bit in PCDRH or PCDRL, and the register value is read from PCDRH and PCDRL
regardless of the state of the pin.
If a pin is set to the general input function, the pin state, not the register value, will be returned if
PCDRH or PCDRL is read. Also, if a value is written to PCDRH or PCDRL, although the value
will actually be written, it will have no influence on the state of the pin. Table 22.6 summarizes
the PCDRH and PCDRL read/write operations.
Bits 15 to 6 in PCDRH are reserved. These bits are read as 0. The write value should always be 0.
PCDRH and PCDRL are initialized to H'0000 by a power-on reset or in deep standby mode. These
registers are not initialized either by a manual reset or by switching to sleep mode or software
standby mode.
• Port C data register H (PCDRH)
• Port C data register L (PCDRL)
