STA33013TR

2.0 digital audio processor with FFX digital modulator and analog and digital inputs

STMicroelectronics 

STA330

Serial digital audio interface (SAI)

8.5

SAI pass-through

A configuration is available which allows the SAI input signal to be passed straight to the

digital output. The STA330 is able to translate the incoming serial audio interface signal from

SAI-in to a different output format on SAI-out. So the SAI pass-through enables devices to

be cascaded, even devices with slightly different protocols.

The pass-through is set by programming register PWMINT1 on page 49 with the value 0x00

and register PWMINT2 with the value 0x01.

SAI-in protocol is set up with registers S2PCFG0 on page 39 and S2PCFG1 and SAI-out

protocol with P2SCFG0 on page 41 and P2SCFG1.

Input and output data sampling frequencies must be the same.
