Upon reset, PCR6 is initialized to H'00.
PCR6 is a write-only register, which always reads all 1s.

PUCR6 controls whether the MOS pull-up of each of the port 6 pins P6
7 to 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.
