When trying to make a change to this bit, new value of PNPCVS must be complementary to the old
one to make an effective change. For example, the user must set PNPCVS to 0 first and then
reset it to 1 to reset these PnP registers if the present value of PNPCVS is 1. The corresponding
power-on setting pin is NDTRA (pin 52).
