DDR memory module temp sensor with integrated SPD
7.10.1   Write operations
7.10.1.1   Byte Write
In Byte Write mode the master creates a START condition and then broadcasts the slave
address, byte address, and data to be written. The slave acknowledges all 3 bytes by
pulling down the SDA line during the ninth clock cycle following each byte. The master
creates a STOP condition after the last ACK from the slave, which then starts the internal
write operation (see Figure 11
). During internal write, the slave will ignore any read/write
request from the master.
 
7.10.1.2   Page Write
The SE97B contains 256 bytes of data, arranged in 16 pages of 16 bytes each. The page
is selected by the four Most Significant Bits (MSB) of the address byte presented to the
device after the slave address, while the four Least Significant Bits (LSB) point to the byte
within the page. By loading more than one data byte into the device, up to an entire page
can be written in one write cycle (see Figure 12
). The internal byte address counter will
increment automatically after each data byte. If the master transmits more than
16 data bytes, then earlier bytes will be overwritten by later bytes in a wrap-around
fashion within the selected page. The internal write cycle is started following the STOP
condition created by the master.
