CAT28F001
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 V HH . 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 V IH or V IL .

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.

BYTE PROGRAM
SUCCESSFUL
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.
