EM78P458/459
OTP ROM
• If enabled, the comparator remains active and the interrupt remains functional, even under SLEEP
mode.
• If a mismatch occurs, the interrupt will wake up the device from SLEEP mode.
• The power consumption should be taken into consideration for the benefit of energy conservation.
• If the function is unemployed during SLEEP mode, turn off comparator before entering into sleep
mode.
