1.8.3 Interrupt Basic Timing
Figure 1-9 shows the basic interrupt timing.
As shown in the figure, when an interrupt factor is generated, the interrupt factor is sampled at the falling edge of
CLK and an interrupt request (IRQ) is set at the first half of S1.
When an interrupt condition is established and the CPU receives an interrupt, the interrupt routine will start
beginning from the next machine cycle.
