Description
If a port B read is performed while PBDDR bits are
set to 1, the PBDR values are read. If a port B read
is performed while PBDDR bits are cleared to 0, the
pin states are read.
Description
When a pin is specified as an input port, setting the
corresponding bit to 1 turns on the input pull-up MOS
for that pin.
