C 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.

C 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).
