Port B Input Pull-Up Mos; Table 7.7 Input Pull-Up Mos States (Port B) - Renesas H8S/2111B Hardware Manual

• PB0/WUE0/LSMI
The pin function is switched as shown below according to the combination of the LSMIE bit in
HICR0 of the host interface (LPC) and the PB0DDR bit.
LSMIE
PB0DDR
Pin Function PB0 input pin
Notes: 1. When the LSMIE bit in HICR0 is set to 1, the PB0DDR bit should be cleared to 0.
2. This pin can always be used as the WUE0 or LSMI input pin.

Port B Input Pull-Up MOS

Port B has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
When a pin is designated as an on-chip peripheral module output pin, the input pull-up MOS is
always off.
Table 7.7 summarizes the input pull-up MOS states.
