TransmissionwithoutAcknowledge
Avoiding to detect the acknowledge of the audio-
processor, the
μ
P can use a simplier transmission:
simply it waits one clock without checking the slave
acknowledging,and sendsthenew data.
This approach of course is less protected from
misworking and decreasesthe noiseimmunity.
InterfaceProtocol
The interface protocolcomprises:
A start condition (S)
A chip address byte, containing the TDA7300
address(the 8th bit of the byte must be 0). The
TDA7300 mustalways acknowledge at the end
of each transmittedbyte.
A sequenceof data(N-bytes + acknowledge)
A stop condition (P)
