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.
