MCU Operation Sequence:
The MCU operates in the sequence shown in figures 16 to 18. It is reset by
an asynchronous RESET input, regardless of its state.
The low-power mode operation sequence is shown in figure 18. 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.
