PDR6 is an 8-bit register that stores data for port 6 pins P6
7 to P60.
If port 6 is read while PCR6 bits are set to 1, the values stored in PDR6 are read, regardless of the
actual pin states. If port 6 is read while PCR6 bits are cleared to 0, the pin states are read.
Upon reset, PDR6 is initialized to H'00.

PCR6 is an 8-bit register for controlling whether each of the port 6 pins P6
7 to P60 functions as an
input pin or output pin.
Setting a PCR6 bit to 1 makes the corresponding pin (P6
7 to P60) an output pin, while clearing the
bit to 0 makes the pin an input pin. PCR6 and PDR6 settings are valid when the corresponding
pins are designated for general-purpose input/output by bits SGS3 to SGS0 in LPCR.
