8. Full Status Check Procedure
6. Word Program Procedure
SR3 MUST be cleared before the Write State Machine allows
further program attempts.
If an error is detected, clear the status register before
continuing operations – only the Clear Status Register
command clears the status register error bits.
Operation
Repeat for subsequent Word Program operations.
Full status register check can be done after each program, or
after a sequence of program operations.
Write FF after the last operation to set to the Read state.
