7.29. Program Security Registers (42H)

The Program Security Registers command is similar to the Page Program command. It allows from 1 to 1024

bytes Security Registers data to be programmed. A Write Enable (WREN) command must previously have been

executed to set the Write Enable Latch (WEL) bit before sending the Program Security Registers command. The

Program Security Registers command is entered by driving CS# Low, followed by the command code (42H),

three address bytes and at least one data byte on SI. As soon as CS# is driven high, the self-timed Program

Security Registers cycle (whose duration is tPP) is initiated. While the Program Security Registers cycle is in

progress, the Status Register may be read to check the value of the Write in Progress (WIP) bit. The Write in

Progress (WIP) bit is 1 during the self-timed Program Security Registers cycle, and is 0 when it is completed. At

some unspecified time before the cycle is completed, the Write Enable Latch (WEL) bit is reset.

If the Security Registers Lock Bit (LB3-1) is set to 1, the Security Registers will be permanently locked.

Program Security Registers command will be ignored.
