PUCR6 controls whether the MOS pull-up of each port 6 pin P6₇–P6₀ is on or off. When a PCR6
bit is cleared to 0, setting the corresponding PUCR6 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, PUCR6 is initialized to H'00.
