The OTP DATA PROTECT (A5h-10h) command is used to protect the data in the OTP
area. After the data is protected, it cannot be programmed further. When the OTP area is
protected, the pages within the area are no longer programmable and cannot be unpro-
tected.
To use the OTP DATA PROTECT command, issue the A5h command. Next, issue the fol-
lowing 5 address cycles: 00h-00h-01h-00h-00h. Finally, issue the 10h command.
R/B# goes LOW while the OTP area is being protected. The protect command duration is
similar to a normal page programming operation,
command is the only command valid during the OTP DATA PROTECT operation. Bit 5 of
the status register will reflect the state of R/B#.
When the device is ready, read bit 0 of the status register to determine if the operation
passed or failed (see Table 11 on page 26).
