TDA7572

30/64

Read Procedure:

Two possible read procedures are possible:

without increment: the I bit is set to 0 and the register is addressed by the subaddress

sent in the previous write procedure. Only this register is written by the data following

the address.

with increment: the I bit is set to 1 and the first register read is the one addressed by

subaddress sent in the previous write procedure. Are written the register from this

address up to stop bit or the reaching of last register.

Example of read instruction with increment and previous addressing by write instruction and

restart bit (Sr)

In the following tables are reported the meaning of each I2C bus present in the device.
