Protection Register Programming Flowchart

FULL STATUS CHECK PROCEDURE

Program Protection Register operation addresses must be

within the Protection Register address space. Addresses

outside this space will return an error.

Repeat for subsequent programming operations.

Full Status Register check can be done after each program, or

after a sequence of program operations.

Write 0xFF after the last operation to set Read Array state.

Only the Clear Staus Register command clears SR[1, 3, 4].

If an error is detected, clear the Status register before

attempting a program retry or other error recovery.
