ADDRESS
DEVICE
7. 3 Sequential Read
When the E
start condition both in current address read and random read, it responds with an acknowledge.
An 8-bit data is then sent from the E
automatically incremented at the falling edge of the SCL clock for the 8th bit data.
When the master device responds with an acknowledge, the data at the next memory address is transmitted.
Response with an acknowledge by the master device has the memory address counter in the E
incremented and makes it possible to read data in succession. This is called “Sequential Read”.
The master device outputs stop condition not an acknowledge, the reading of E
Data can be read in succession in the sequential read mode. When the memory address counter reaches the last
word address, it rolls over to the first word address.
