Figure 15 Direct Transition Timing

MCU Operation Sequence: The MCU operation flow is shown in figures 16 and 17.

RESET input is

asynchronous, and causes an immediate transition to the reset state from any MPU operation state.

The low-power mode operation sequence is shown in figure 17. With the IE flag cleared and an interrupt

flag set together with its interrupt mask cleared, if a STOP/SBY instruction is executed, the instruction is

cancelled (regarded as an NOP) and the following instruction is executed. Before executing a STOP/SBY

instruction, make sure all interrupt flags are cleared or all interrupts are masked.
