State
S1
S2
Normal operation: Normal array reads and
First program hardware interlock write:
register accesses. Block protect information
and pulse width timing control can be
modified.
Normal read operation. Array accepts
programming writes. Normal register
accesses. CMFRCTL write cannot change
EHV. If write is to a register other than
CMFRMCR, no data is stored in program
page buffers; CMFR remains in S2.

Hardware interlock: Successful programming
write to any array location. Latches selected
data word into programming page buffer;
address latched to select location to
program. Bit that has been written remains
in program buffer until another write to it, or
SES is cleared, or a program margin read
determines bit needs no modification by
program operation. If write is to a register
(except CMFRMCR), no data is stored in
program page buffers, and CMFR remains
in S2. Writing to CMFRMCR does not allow
array to be programmed.
