Loop
Operation Command
Repeat for subsequent Word Program 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 to the Read Array
state.
Operation
If an error is detected, clear the Status Register before
continuing operations - only the Clear Staus Register
command clears the Status Register error bits.
