X4C105
Page Write
The device is capable of a page write operation. It is initiated
in the same manner as the byte write operation; but instead
of terminating the write cycle after the first data byte is
transferred, the master can transmit an unlimited number of
8-bit bytes. After the receipt of each byte, the device will
respond with an acknowledge, and the address is internally
incremented by one. The page address remains constant.
When the counter reaches the end of the page, it “rolls over”
and goes back to ‘0’ on the same page. This means that the
master can write 16 bytes to the page starting at any location
on that page. If the master begins writing at location 10, and
loads 12 bytes, then the first 5 bytes are written to locations
10 through 15, and the last 7 bytes are written to locations 0
through 6. Afterwards, the address counter would point to
location 7 of the page that was just written. See Figure 6. If the
master supplies more than 16 bytes of data, then new data
over-writes the previous data, one byte at a time.
The master terminates the data byte loading by issuing a
stop condition, which causes the device to begin the
nonvolatile write cycle. As with the byte write operation, all
inputs are disabled until completion of the internal write
cycle. Refer to Figure 7 for the address, acknowledge, and
data transfer sequence.
Stops and Write Modes
Stop conditions that terminate write operations must be sent
by the master after sending at least 1 full data byte plus the
subsequent ACK signal. If a stop is issued in the middle of a
data byte, or before 1 full data byte plus its associated ACK
is sent, then the device will reset itself without performing the
write. The contents of the array will not be affected.
