SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
s
A start condition (S)
s
A chip address byte
s
A subaddress bytes
s
A sequence of data (N byte + acknowledge)
s
A stop condition (P)
ACK = Acknowledge
S = Start; P = Stop
A = Address
B = Auto Increment
EXAMPLES
No Incremental Bus
The TDA7467 receives a start condition, the correct chip address, a subaddress with the MSB = 0 (no
incremental bus), N-data (all these data concern the subaddress selected), a stop condition.
Incremental Bus
The TDA7467 receive a start conditions, the correct chip address, a subaddress with the MSB = 1 (incre-
mental bus): now it is in a loop condition with an autoincrease of the subaddress whereas SUBADDRESS
from "1XXXX1XX" to "1XXX111" of DATA are ignored.
The DATA 1 concern the subaddress sent, and the DATA 2 concerns the subaddress sent plus one sent
in the loop etc, and at the end it receivers the stop condition.
