FULL STATUS CHECK PROCEDURE
Operation Command
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.
Operation
SR[3] must be cleared before the Write State Machine will
allow further program attempts.
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.
