Section 8 I/O Ports
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 the port 8 pins P8
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. PCR8 and PDR8 settings are valid when the corresponding
pins are designated for general-purpose input/output by bits SGS3 to SGS0 in LPCR.
Upon reset, PCR8 is initialized to H'00.
PCR8 is a write-only register, which is always read as all 1s.
