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