SLx 24C01/02/P
6.3 Sequential Read
A sequential read is initiated in the same way as a current read or a random read except
that the master acknowledges the data byte transmitted by the EEPROM. The EEPROM
then continues the data transmission. The internal address counter is incremented by
one during each data byte transmission.
A sequential read allows the entire memory to be read during one read operation. In the
SLx 24C02/P, after the highest addressable memory location is reached, the internal
address pointer “rolls over” to the address 0 and the sequential read continues. In the
SLx 24C01/P, there is no “roll over”.
The transmission is terminated by the master by releasing the SDA line (no
acknowledge) and generating a STOP condition (see figure 13).
