ADDRESS
DEVICE
7. 3 Sequential read
When the S-24C04C receives a 7-bit device address and a 1-bit read / write instruction code set to “1” following a
start condition both in current address read and random read, it responds with an acknowledge.
When an 8-bit data is output from the S-24C04C synchronous to the SCL clock, the address counter is
automatically incremented.
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 S-24C04C
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 S-24C04C is ended.
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.
