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 to the Read Array
state.
SR[3] MUST be cleared before the Write State Machine will
allow further program attempts.
If an error is detected , clear the Status Register before
continuing operations - only the Clear Staus Register
command clears the Status Register error bits .
