SBIREQ

0: SBI not requested

R(Note 1)

SBI request bit

1: SBI requested

Note 1: This bit can only be cleared (see below)

The System Break Interrupt (SBI) is an interrupt request generated by a falling edge on the SBI# signal input pin.

When a falling edge on the SBI# signal input pin is detected and this bit is set to "1", a system break interrupt

(SBI) request is generated to the CPU.

This bit cannot be set to "1" in software, it can only be cleared.

To clear this bit to "0", follow the procedure described below.

1. Write "1" to the SBI request bit.

2. Write "0" to the SBI request bit.

Note: • Unless this bit is set to "1", do not perform the above clearing operation.
