CHAPTER 14 ICU (INTERRUPT CONTROL UNIT)

317

14.3 NOTES FOR REGISTER SETTING

There is no register setting flow in relation to the ICU.

With regard to the interrupt mask registers, the initial setting is “initial = 0= mask” after start up. Therefore, enough

masks must be cleared to provide sufficient interrupts for the CPU’s start-up processing. This is always necessary

when battint_intr = NMI.

The initial setting for battint_intr is “initial = 0 = NMI”. A “1” must be written to the register to switch this setting to

Int0.

soft_intr is a software interrupt that is output to Int0 by setting 1 to the SOFTINTREG register. Writing a “0” clears

the interrupt.
