In mode 7, if a pin is in the input state in accordance with the settings in the SCI's SCMR, SMR,
and SCR, and in DDR, setting the corresponding PAPCR 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 power-on reset, and in hardware standby
mode. The prior state is retained by a manual reset or in software standby mode.
