SE97B
DDR memory module temp sensor with integrated SPD
7.10.3.3 Sequential read
If the master acknowledges the first data byte transmitted by the SE97B, then the device
will continue transmitting as long as each data byte is acknowledged by the master
(Figure 17
). If the end of memory is reached during sequential Read, the address counter
will wrap around to the beginning of memory, and so on. Sequential Read works with
either Immediate Address Read or Selective Read, the only difference being the starting
byte address.
