Pin Function
Note: *
The pin function is switched as shown below according to the state of the PBnDDR bit.
The pin function is switched as shown below according to the combination of the LSCIE bit in
HICR0 of the host interface (LPC) and the PB1DDR bit.

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.
