I²C and mode control
TDA7572
Read Procedure:
Two possible read procedures are possible:
1. 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.
2. 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.
