Hello,

What is the difference between Parameter Register's Frame Size and SAI Transmit Configuration 4 Register 's Frame Size?

Thank you.

Hi ma

Parameter Register's (read only) shows sai configuration implemented in that processor:

for example FRAME (Frame Size) =5 : The maximum number of slots per frame is 2^FRAME: 32

This corresponds description for SAI Transmit Configuration 4 Register (TCR4):

"FRSZ -The maximum supported frame size is 32 words."

Hi,

So Parameter Register's Frame Size is only going to be 5 at most, even if it has 4 bits, right?

Parameter Register shows what max. Frame Size is implemented in

that processor silicon sai module. In other processors silicons it may have other values.
