Page write

The page write mode allows up to 256 bytes to be written in a single write cycle, provided they are all located on

the same page in the memory. This means that the most significant memory address bits, from A17 to A8, are the

same. If more bytes are sent than fit up to the end of the page, a roll-over occurs: the bytes exceeding the page

end are written on the same page, from location 0.

The bus controller sends from 1 to 256 bytes of data, each of which is acknowledged by the device if the

addressed bytes are not write-protected through the SWP setting or through WC pin (driven low). In the opposite

case, when the addressed bytes are write-protected by SWP setting or WC pin (driven high), the contents of the

addressed memory location are not modified, and each data byte is followed by a NO ACK, as shown in Figure 7.

After each transferred byte, the internal page address counter is incremented.

The transfer is terminated by the bus controller generating a stop condition.
