Hi Divyesh,

Thanks for your question. SCI FIFO status register can give any FIFO level (1-16) you would like. So yes, it can show when 5 words are in FIFO.

Regards,

Vince

Than Why it's not mention in Datasheet and why I can't read FIFO Level 5?

Hi Divyesh,

I apologize for the confusion, this device only has 4 FIFO levels, so it is actually not possible to trigger on FIFO level of 5. That would be a FIFO overflow.

Regards,

Vince
