Note:
The OTP Programming Supply PROGVDD should only be present when programming the OTP. At other times, this pin
should be left unconnected. The LDO12VOUT must be overdriven by an external supply when programming the OTP. At
other times, the voltage at this pin is driven by the internal circuits of the WM8325.
