used after transition to active mode), execute the TEST instruction to the RAM enable flag (RAME) at the

beginning of the program.

MCU Operation Sequence: The MCU operates in the sequence shown in figures 17 to 19. It is reset by an

asynchronous RESET input, regardless of its status.

The low-power mode operation sequence is shown in figure 19. 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/SBYinstruction, make sure all interrupt flags are cleared or all interrupts are masked.
