PDR7 is an 8-bit register that stores data for port 7 pins P7
7 to P70. If port 7 is read while PCR7
bits are set to 1, the values stored in PDR7 are directly read, regardless of the actual pin states. If
port 7 is read while PCR7 bits are cleared to 0, the pin states are read.
Upon reset, PDR7 is initialized to H'00.

PCR7 is an 8-bit register for controlling whether each of the port 7 pins P7
7 to P70 functions as an
input pin or output pin. Setting a PCR7 bit to 1 makes the corresponding pin an output pin, while
clearing the bit to 0 makes the pin an input pin.
Upon reset, PCR7 is initialized to H'00.
PCR7 is a write-only register. All bits are read as 1.
