1. Set the D4INT registers after the PRC3 bit in the PRCR register is set to "1" (write enable).
2. The D40 bit setting is enabled when the VC27 bit in the VCR2 register is set to "1" (low voltage
3. When exiting stop mode using the low voltage detection circuit again after having already done so,
4. The D42 bit setting is enabled when the VC27 bit in the VCR2 register is set to "1" (low voltage
5. The bit is set to "0" by a program. (It remains unchanged even if it is set to "1".)
6. The D4INT register in M32C/84T cannot be used.

Use the following procedure to set the D40 bit to "1":
detection circuit enabled). The D42 bit is set to "0" when the VC27 bit is set to "0" (low voltage
detection circuit disabled).
3
(1) Set the VC27 bit to "1"
(2) Wait td(E-A) ms to start operating the voltage detection circuit
(3) Wait required sampling time (see Table 6.2)
(4) Set the D40 bit to "1"
set the D41 bit to "1" after setting it to "0".
