Port Pull-Up Control Register 6 (PUCR6)
Bit
PUCR6
Initial value
Read/Write R/W
PUCR6 controls whether the MOS pull-up of each of the port 6 pins P6
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.
