Set the PRC3 bit in the PRCR register to 1 (w rite enable) before w riting to the VW1C register.
The value other than the VW1CO and VW1C6 bits remains unchanged after softw are reset, w atchdog timer reset,
and voltage monitor 2 reset.
The VW1C0 bit is enabled w hen the VCA26 bit in the VCA2 register is set to 1 (voltage detection 1 circuit
enabled). Set the VW1C0 bit to 0 (disable), w hen the VCA26 bit is set to 0 (voltage detection 1 circuit disabled).
The VW1C7 bit is enabled w hen the VW1C1 bit is set to 1 (digital filter disabled mode).
