Data Sheet
Byte-Program
The Byte-Program instruction programs the bits in the
selected byte to the desired data. The selected byte must
be in the erased state (FFH) when initiating a Program
operation. A Byte-Program instruction applied to a pro-
tected memory area will be ignored.
Prior to any Write operation, the Write-Enable (WREN)
instruction must be executed. CE# must remain active low
for the duration of the Byte-Program instruction. The Byte-

Program instruction is initiated by executing an 8-bit com-
mand, 02H, followed by address bits [A
address, the data is input in order from MSB (bit 7) to LSB
(bit 0). CE# must be driven high before the instruction is
executed. The user may poll the Busy bit in the software
status register or wait T
self-timed Byte-Program operation. See Figure 7 for the
Byte-Program sequence.
