NOTES:
1. Set the D4INT register after the PRC3 bit in the PRCR register is set to 1 (write enable).
2. Use the following procedure to set the D40 bit to 1:
3. If the Vdet4 detection interrupt has been used to exit wait mode or stop mode, set the D41 bit to 0 and then set it to 1 to use the
4. The D42 bit is enabled when the VC27 bit is set to 1 (Vdet4 detection function used ). The D42 bit becomes 0 when the VC27 bit
5. The D43 bit can be set to 0 by a program. Writing a 1 has no effect.
Vdet4 detection interrupt again to exit these modes.
is set to 0 (Vdet4 detection function not used).
(1) Set the VC27 bit in the VCR2 register to 1
(2) Wait for td(E-A) before the voltage detection circuit starts operating
(3) Wait for required sampling time (See Table "Sampling Period" )
(4) Set the D40 bit to 1
