Table 6.1 Conditions to Generate Low Voltage Detection Interrupt Request

If the D40 bit in the D4INT register is set to "1" (low voltage detection interrupt enabled), low voltage
detection interrupt request is generated when the voltage applied to the V
below Vdet4. The low voltage detection interrupt shares the same interrupt vector with the watchdog timer
interrupt and oscillation stop detection interrupt. The D42 bit in the D4INT register determines whether the
low voltage detection interrupt has been generated. Read the D42 bit using an interrupt routine when using
the low voltage detection interrupt at the same time as the watchdog timer interrupt and oscillation stop
detection interrupt.
Set the D41 bit in the D4INT register to "1" (enabled) to use the low voltage detection interrupt to exit stop
mode or wait mode.
The D42 bit is set to "1" (more or less than Vdet4 detected) as soon as the voltage applied to the V
reaches Vdet4 due to the voltage rise and voltage drop. When the D42 bit setting changes "0" to "1", low
voltage detection interrupt request is generated. Set the D42 bit to "0" (not detected) by program. However,
when the D41 bit is set to "1" and the microcomputer is in stop mode or wait mode, low voltage detection
interrupt request is generated, regardless of the D42 bit setting, if the voltage applied to the V
detected to be higher than Vdet4. The microcomputer then exits stop mode or wait mode.
Table 6.1 shows how a low voltage detection interrupt request is generated.
The DF1 and DF0 bits in the D4INT register determine sampling period that detects the voltage applied to
