Port Control Register 7 (PCR7)
PCR7 is an 8-bit register for controlling whether each of the port 7 pins P7
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. The settings in PCR7 and in PDR7 are valid only
when the corresponding pin is designated in bits SGS3 to SGS0 in LPCR as a general I/O pin.
Upon reset, PCR7 is initialized to H'00.
PCR7 is a write-only register. All bits are read as 1.
