Description
Reserved
The read value is undefined. These bits cannot be
modified.
When a PCR8 bit is cleared to 0, setting the
corresponding PUCR8 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.
Reserved
The read value is undefined. These bits cannot be
modified.
