Byte Write
sequence, by sending a WRITE instruction, a 16−bit address
and data as shown in Figure 5. Only 10 significant address
bits are used by the CAT25080 and 11 by the CAT25160. The
rest are don’t care bits, as shown in Table 11. Internal
programming will start after the low to high CS transition.
During an internal write cycle, all commands, except for
RDSR (Read Status Register) will be ignored. The RDY bit
will indicate if the internal write cycle is in progress (RDY
high), or the device is ready to accept commands (RDY
low).

Page Write
host may continue sending data, up to a total of 32 bytes,
according to timing shown in Figure 6. After each data byte,
the lower order address bits are automatically incremented,
while the higher order address bits (page address) remain
unchanged. If during this process the end of page is
exceeded, then loading will “roll over” to the first byte in the
page, thus possibly overwriting previously loaded data.
Following completion of the write cycle, the CAT25080/160
is automatically returned to the write disable state.
