By Analog Verification: By switching into Extended Mode and sending an ANALOG OTP READ command (#9), pin PROG becomes an output,

sending an analog voltage with each clock representing a sequence of the bits in the OTP register (starting with D45). A voltage of <500mV

indicates a correctly programmed bit (“1”) while a voltage level between 2V and 3.5V indicates a correctly unprogrammed bit (“0”). Any voltage

level in between indicates incorrect programming.
