For i.MX8M Mini part# MIMX8MM6DVTLZAA, is any of the 5 SAI interfaces multiplexed with PCM interface..?
Is there PCM interface available for audio interface in i.MX8M Mini processor..?
Sorry i.MX8MM I2S does not support PCM format which described on Pulse-code modulation - Wikipedia
one can look at sect.3.9.11 SAI/I2S switching specifications
and sai appnotes for other processors, as sai is the same module:
AN12202 Using Synchronous Audio Interface (SAI) on S32K148
