I²C bus interface description
● Interface Protocol
The interface protocol comprises:
– a start condition (S)
– a chip address byte (the LSB bit determines read / write transmission)
– a subaddress byte
– a sequence of data (N-bytes + acknowledge)
– a stop condition (P)
Figure 26. I²C bus interface diagram
S = Start
ACK = Acknowledge
Auto increment
If bit I in the subaddress byte is set to "1", the auto increment of the subaddress is enabled
which is also true for the SPI mode.
Chip-address
For the TDA7415CB the chip address is $8C (10001100).
