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.

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.
