One of my customer is using BF592 for an audio application. He plans to use one Sport RX channel to work in TDM8 mode to receive the data from 21489 and use 4 TX channels of Sports to transmit 4 I2S to 4 DAC. Here is the diagram.
I notice that there are 2 sports on BF592. And each sport has 2 rx and 2 tx channel as blow. In the datasheet, it says the tx and rx channel works in full-duplex mode. So I suppose the TX clk and RX clk could be asynchronous. And also the hardware reference give me serval examples to illustrate how the RX and TX works.
However, this section says the RSCLK is used both for transmit and receive functions.
Does it means that if the SPORT works in the multichannel mode, the RX and TX channels are synchronous with same clock - RSCLK?
So is that possible to use two SPORT to receive 1 TDM8 and transmit 4 I2S on BF592?
