9.12.4
Port B has a built-in MOS input pull-up function that can be controlled by software. This MOS
input pull-up function can be used in modes 6 and 7, and can be specified as on or off on an
individual bit basis.
When a PBDDR bit is cleared to 0 in mode 6 or 7, setting the corresponding PBPCR bit to 1 turns
on the MOS input pull-up for that pin.
The MOS input pull-up function is in the off state after a reset, and in hardware standby mode.
The prior state is retained in software standby mode.
Table 9.23 summarizes the MOS input pull-up states.
