14.1.5 Port C IO Register H and L (PCIORH and PCIORL)
PCIORH and PCIORL are 16-bit readable/writable registers that select the input/output directions
of the port C pins. Bits PC20IOR to PC0IOR correspond to pins PC20 to PC00 (the pin name
abbreviations for multiplexed functions are omitted). PCIORH is enabled when a port C pin
functions as a general input/output (PC20 to PC16), otherwise, disabled. PCIORL is enabled when
a port C pin functions as a general input/output (PC15 to PC00), otherwise, disabled.
Setting a bit in PCIORH and PCIORL to 1 makes the corresponding pin function as an output and
clearing a bit in PCIORH and PCIORL to 0 makes the pin function as an input.
Bits 15 to 5 in PCIORH are reserved. These bits are always read as 0. The write value should
always be 0.
The initial values of PCIORH and PCIORL are H'0000.
14.1.6 Port D IO Register L (PDIORL)
PDIORL is a 16-bit readable/writable register that selects the input/output directions of the port D
pins. Bits PD7IOR to PD0IOR correspond to pins PD7 to PD0 (the pin name abbreviations for
multiplexed functions are omitted). PDIORL is enabled when a port C pin functions as a general
input/output (PD7 to PD0), otherwise, disabled.
Setting a bit in PDIORL to 1 makes the corresponding pin function as an output and clearing a bit
in PDIORL to 0 makes the pin function as an input.
Bits 15 to 8 in PDIORL are reserved. These bits are always read as 0. The write value should
always be 0.
The initial value of PDIORL is H'0000.
