Programming Verification
After programming, the programmed OTP bits are verified in following two ways:
By Digital Verification: This is simply done by sending a READ OTP command (#0FH, Refer to
structure of this register is the 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.
