Serial data pin. Output port when reading and
input port when writing. Can be assigned as a
Input/push-pull output port.
Serial clock pin. Input only pin.
Power supply pin for EPROM cell writing
(indicates that OTP enters into the writing mode).
When 12.5 V is applied, OTP is in writing mode
and when 5 V is applied, OTP is in reading mode.
