LSMIE
HI12E
PB0DDR
Pin Function
Notes: 1. When bit LSMIE is set to 1 in HICR0, bits HI12E and PB0DDR should be cleared to 0.
7.12.5
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.
Table 7.7
Legend:
Off:
On/Off: On when the pin is in the input state, PBDDR = 0, and PBODR = 1; otherwise off.

PB0/WUE0/LSMI
The pin function is switched as shown below according to the combination of the HI12E bit in
SYSCR2, the LSMIE bits in HICR0 of host interface (LPC), and the PB0DDR bit.
Input pull-up MOS is always off.
2. This pin can always be used as the WUE0 or LSMI input pin.
