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.
