PUCR5 bits control the on/off state of pin P57–P50 MOS pull-ups. 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—P5n/WKPn/SEGn+1 Pin Function Switch (WKPn): When pin P5n/WKPn/SEGn+1 is not
used as a SEGn+1 pin, this bit selects whether it is used as
P5n or as WKPn.
Bit n: WKPn

Description
Functions as P5n I/O pin
Functions as WKPn input pin
(initial value)
(n = 7 to 0)
Note: For information on use as a SEGn+1 pin, see 13.2.1, LCD Port Control Register (LPCR).
