Q&A-3

Interrupt

Yes. But there can be a chance that the microcomputer runs away out of control if an interrupt

request occurs in changing the value of INTB. So it is not recommended to frequently change the

value of INTB while a program is being executed.

Is it possible to change the value of the interrupt table register (INTB) while a program is being

executed?
