Function
PB0/D0/WUE0/HIRQ3/LSMI *
The pin function is switched as shown below according to the combination of the operating
mode, the HI12E and CS3E bits in SYSCR2, the LSMIE bits in HICR0 of host interface
(LPC), the ABW bit in WSCR, and the PB0DDR bit.

Except when used as a data bus pin, this pin can always be used as the WUE0 input
pin. The HIRQ3 output pin and LSMI I/O pin can only be used in mode 2 or 3 (EXPE =
0).
In mode 1, 2, 3 (EXPE = 1), clear the LSMIE bit to 0.
Not supported by the H8S/2148B and H8S/2145B (5-V version).
