Figure 13-90 on page 4174 of Document Number: IMX8MMRM Rev. 2, 08/2019 - the i.MX 8M Mini Applications Processor Reference Manual shows a diagram of the SPDIF clocking that includes an Asynchronous Sample Rate Converter (ASRC) block. It also states that the SPDIF Rx clock is sent to the ASRC. But the ASRC is not mentioned anywhere else in the document and I could not find any other documentation on how to enable and use the ASRC. Is there an ASRC availible on this IC? If so could we get some documentation on how to use it?
