Port Pull-Up Control Register 5 (PUCR5)
PUCR5 controls whether the MOS pull-up of each of port 5 pins P5
PCR5 bit is cleared to 0, setting the corresponding PUCR5 bit to 1 turns on the MOS pull-up for
the corresponding pin, while clearing the bit to 0 turns off the MOS pull-up.
Upon reset, PUCR5 is initialized to H'00.
Port Mode Register 5 (PMR5)
PMR5 is an 8-bit read/write register, controlling the selection of pin functions for port 5 pins.
Upon reset, PMR5 is initialized to H'00.
