Repeat for subsequent bytes.
Full Status check can be done after each byte or after a sequence
of bytes.
Write FFH after the last byte programming operation to reset the
device to Read Array Mode.

Check SR.3
1 = Byte Program Error
SR.3 MUST be cleared, if set during a program attempt, before
further attempts are allowed by the Write State Machine.
SR.3 is only cleared by the Clear Status Register Command, in
case where multiple bytes are programmed before full status is
checked.
If error is detected, clear the Status Register before attempting retry
or other error recovery.

IN-SYSTEM OPERATION
For on-board programming, the RP pin is the most
convenient means of altering the boot block. Before
issuing Program or Erase confirms commands, RP must
transition to VHH. Hold RP at this high voltage throughout
the program or erase interval (until after Status Register
confirm of successful completion). At this time, it can
return to VIH or VIL.
