Function
PB2/D2/:8(5*
The pin function is switched as shown below according to the combination of the operating
mode, the HI12E and CS3E bits in SYSCR2, the ABW bit in WSCR, and the PB2DDR bit.
PB1/D1/:8(4/HIRQ4/LSCI*
The pin function is switched as shown below according to the combination of the operating
mode, the HI12E and CS4E bits in SYSCR2, the LSCIE bits in HICR0 of host interface (LPC),
the ABW bit in WSCR, and the PB1DDR bit.
