Manufacturer identity
The second OTP feature defines the manufacturer
identity. A 3-bit code MF[2:0] is used to define this
parameter. The default manufacturer identity is
MF[2:0] = 000.
17.3
Seal bit
Module maker programming is performed in a special
mode; the calibration mode MM. This mode is entered via
the interface command, MM. To prevent wrongful
programming, a seal bit prevents the device from entering
the calibration mode. This seal bit, once programmed,
cannot be reversed, thus further changes in programmed
values are not possible. However it is possible to disable
all programmed values by applying the disable OTP
command.
Applying the programming voltages when not in MM mode
will have no effect on the programmed values.

RCHITECTURE
The OTP circuitry in the PCF8813 contains nine bits of
data: five for V
LCD
calibration, three for the manufacturer
identity and one for the seal bit. The circuitry for 1-bit is
called an OTP slice. Each OTP slice consists of two main
parts: the OTP cell (a non-volatile memory cell) and the
shift register cell (a flip-flop). The OTP cells are accessible
only through their shift register cells; both reading-from
and writing-to the OTP cells are performed with the shift
register cells, but only the shift register cells are visible to
the rest of the circuit. The basic OTP architecture is shown
in Fig.48.
