Programming Verification.
By Digital Verification: This is simply done by sending a READ OTP command (#0FH, Refer to
same as for the OTP PROG or OTP WRITE commands.
By Analog Verification: By sending an ANALOG OTP READ command (#09H), pin PROG becomes an output, sending an analog voltage with
each clock, representing a sequence of the bits in the OTP register. A voltage of <500mV indicates a correctly programmed bit (“1”) while a
voltage level between 2.2V and 3.5V indicates a correctly unprogrammed bit (“0”). Any voltage level in between indicates improper programming.
