Effective timing after controlling interrupt bit

Case A in Figure 19 shows the effective time after controlling the Interrupt Enable Registers (IE, IE1,
IE2, and IE3).

Figure 19. Case A: Effective Timing of Interrupt Enable Register

Case B in Figure 20 shows the effective time after controlling Interrupt Flag Registers.

Figure 20. Case B: Effective Timing of Interrupt Flag Register

Interrupt Enable Register

command

Next Instruction

After executing IE set/clear,
enable register is effective.

Interrupt Flag Register

Command

Next Instruction

After executing next instruction,
interrupt flag result is effective.
