The read value is undefined. These bits cannot be
modified.
When a PCR1 bit is cleared to 0, setting the
corresponding PUCR1 bit to 1 turns on the pull-up MOS
for the corresponding pin, while clearing the bit to 0
turns off the pull-up MOS.
8.1.4 Port Mode Register 1 (PMR1)
PMR1 controls the selection of functions for port 1 pins.
