1. NMI, IRQ0 to IRQ15*
2. NMI, IRQ0 to IRQ15*
3. IRQ8 to IRQ15 are not supported by the H8S/2424 group.

Program execution state
From any state, a transition to hardware standby mode occurs when STBY is driven low.
From any state except hardware standby mode, a transition to the reset state occurs
when RES is driven low.
(8-bit timer interrupts are valid when MSTP0 = 0.)
