Section 9 I/O Ports
9.7.5
Port B has an on-chip MOS input pull-up function that can be controlled by software. MOS input
pull-up can be specified as on or off on an individual bit basis.
In modes 4 to 6, if a pin is in the input state in accordance with the settings in PFCR, in the TPU’s
TIOR, and in DDR, setting the corresponding PBPCR bit to 1 turns on the MOS input pull-up for
that pin.
In mode 7, if a pin is in the input state in accordance with the settings in the TPU’s TIOR and in
DDR, 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 by a manual reset or in software standby mode.
Table 9-13 summarizes the MOS input pull-up states.
