PUCR5 controls whether the MOS pull-up of each of port 5 pins P5₇ 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/WKP_n/SEG_n+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.
