Note:
If the Error LED flashing out request signal (Y2E) is turned on, the flashing LEDs for E1 and E2 go out.
Also, while the Error LED flashing out request signal (Y2E) is on, the LEDs for E1 and E2 will not flash,
even if a recoverable error or a warning error occurs. However, these functions are not affected by error
log processing, so the error contents remain in the log.
