Port Pull-Up Control Register 1 (PUCR1)
PUCR1 controls whether the MOS pull-up of each of the port 1 pins P1
or off. When a PCR1 bit is cleared to 0, setting the corresponding PUCR1 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.
Note: * Pin 1
Port Mode Register 1 (PMR1)
PMR1 is an 8-bit read/write register, controlling the selection of pin functions for port 1 pins.
