Page Write

The Page Write mode allows up to N(1) bytes 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, A17/A8, are the same. If more bytes are sent than will fit up to the end

of the page, a condition known as “roll-over” occurs. In case of roll-over, the first bytes of the

page are overwritten.

The bus master sends from 1 to N(1) bytes 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 received by the device is

not acknowledged, as shown in Figure 6. After each byte is transferred, the internal byte

address counter is incremented. The transfer is terminated by the bus master generating a

Stop condition.

1. N is the number of bytes in a page.
