Port Data Register 8 (PDR8)
PDR8 is an 8-bit register that stores data for port 8 pins P8
bits are set to 1, the values stored in PDR8 are read, regardless of the actual pin states. If port 8 is
read while PCR8 bits are cleared to 0, the pin states are read.
Upon reset, PDR8 is initialized to H'00.
Port Control Register 8 (PCR8)
PCR8 is an 8-bit register for controlling whether each of the port 8 pins P8
input or output pin. Setting a PCR8 bit to 1 makes the corresponding pin an output pin, while
clearing the bit to 0 makes the pin an input pin. The settings in PCR8 and in PDR8 are valid only
when the corresponding pin is designated in bits SGS3 to SGS0 in LPCR as a general I/O pin.
Upon reset, PCR8 is initialized to H'00.
PCR8 is a write-only register. All bits are read as 1.
