The OTP area is protected on a block basis. To protect a block, set the device to OTP
protect mode, then issue the PROGRAM PAGE (80h-10h) command and write OTP ad-
dress 00h, 00h, 00h, 00h. To set the device to OTP protect mode, issue the SET FEA-
TURE (EFh) command to 90h (feature address) and write 03h to P1, followed by three
cycles of 00h to P2-P4.
After the data is protected, it cannot be programmed further. When the OTP area is pro-
tected, the pages within the area are no longer programmable and cannot be unprotected.
To use the PROGRAM PAGE command to protect the OTP area, issue the 80h com-
mand, followed by n address cycles, write 00h data, data cycle of 00h, followed by the
10h command. (An example of the address sequence is shown in the following figure.) If
an OTP DATA PROGRAM command is issued after the OTP area has been protected, R/
B# will go LOW for
The READ STATUS (70h) command is the only valid command for reading status in
OTP operation mode. Bit 5 of the status register reflects the state of R/B#.
When the device is ready, read bit 0 of the status register to determine whether the oper-
ation passed or failed (see Status Operations).
