PB7/WUE7, PB6/WUE6, PB5/WUE5, PB4/WUE4, PB3/WUE3, PB2/WUE2
The pin function is switched as shown below according to the status of the PBnDDR bit.
PB1/WUE1/LSCI
The pin function is switched as shown below according to the combination of the HI12E bit in
SYSCR2, the LSCIE bits in HICR0 of host interface (LPC), and the PB1DDR bit.
2. This pin can always be used as the WUE1 or LSCI input pin.

Description
Reading PBPIN always returns the pin states.
PBPIN has the same address as P8DDR. If a write
is performed, data will be written to P8DDR and
the port 8 settings will change.
