• Manufacturer: RENESAS [Renesas Technology Corp]

Notes: 1. When bit LSMIE is set to 1 in HICR0, bits HI12E and PB0DDR should be cleared to 0.
8.12.5
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.

Function
PB0/D0/:8(3/HIRQ3//60,*
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.

Port B Input Pull-Up MOS
Except when used as a data bus pin, this pin can always be used as the :8(3 input
pin. The HIRQ3 output pin and /60, 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.
