Help with SAI peripheral to replace I2S peripheral

[CLeo.1]

Hello! Just a quick question, I just need some help figuring out what is what.

I am coming from the I2S peripheral and setting up the SAI peripheral and to use the I2S protocol, it's that not straight forward.

I am curious if anyone can tell me what is what

The SAI has

Audio Data Size

Frame length

and Slot numbers

For the I2S equivalents I believe

Audio Data Size = DATALEN

Frame Length = CHANNEL LENGTH

But what the heck is slots?

Slots are channels. Everything else is very clearly illustrated in a RM figure mentioned in my previous answer...
