8.36 SECURITY INFORMATION ROW

The security Information Row is comprised of an additional 4 x 256 bytes of programmable information. The

security bits can be reprogrammed by the user. Any program security instruction issued while an erase, program

or write cycle is in progress is rejected without having any effect on the cycle that is in progress.

Bit 7~4 of the Function Register is used to permanently lock the programmable memory array.

When Function Register bit IRLx =

“0”, the 256 bytes of the programmable memory array can be programmed.

When Function Register bit IRLx

= “1”, the 256 bytes of the programmable memory array function as read only.
