Page Write

The Page Write mode allows up to 256 byte to be written in a single Write cycle, provided

that they are all located in the same page in the memory: that is, the most significant

memory address bits, b16-b8, are the same. If more bytes are sent than will fit up to the end

of the page, a “roll-over” occurs, i.e. the bytes exceeding the page end are written on the

same page, from location 0.

The bus master sends from 1 to 256 byte of data, each of which is acknowledged by the

device if Write Control (WC) is low. If Write Control (WC) is high, the contents of the

addressed memory location are not modified, and each data byte is followed by a NoAck, as

shown in Figure 8. After each transferred byte, the internal page address counter is

incremented.

The transfer is terminated by the bus master generating a Stop condition.
