PUCR5 controls whether the MOS pull-up of each of port 5 pins P5
7 to P50 is on or off. When a
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.

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.
Bit n: P5
n/WKPn/SEGn+1 pin function switch (WKPn)
When pin P5n/
WKPn/SEGn+1 is not used as SEG
n+1, these bits select whether the pin is used as
P5n or
WKP
n.
