Port Control Register 9 (PCR9)
PCR9 is an 8-bit register for controlling whether each of the port 9 pins P9
input or output pin. Setting a PCR9 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 PCR9 and in PDR9 are valid only
when the corresponding pin is designated in bits SGS3 to SGS0 in LPCR as a general I/O pin.
Upon reset, PCR9 is initialized to H'00.
PCR9 is a write-only register. All bits are read as 1.
