[alsa-devel] Configuring McBSP word length for ICS-43432

Hello,

I am trying to configure ICS-43432 MEMS mic with TM320DM365 processor's
McBSP interface. The data sheet for ICS-43432 says that it outputs 24-bits
data, i.e., 24 bit word length, but requires 64SCK cycles. Does this mean
the word length (RWDLEN1 bit in RCR register) for McBSP should be set to
32-bits or 24-bits?

Thank you,
Ankhit
