Hi joakim.

Because I've been looking at the 52810 manual and uart has been removed, so I did not see this 6-byte RX FIFO, thanks for your answer.

Hi Stayhungry!

I would recommend that you read about the UART in the product specification, as you will find all the information you need there.
Especially take a look at the reception section of the UART;

"The UART receiver chain implements a FIFO capable of storing six incoming RXD bytes before data is overwritten. Bytes are extracted from this FIFO by reading the RXD register."

You can read more about the FIFO library here.

"The FIFO library provides a simple circular buffer implementation for storing bytes."

So in short, the UART RX FIFO, is a buffer where the incoming RXD bytes are stored.

Best regards,
Joakim.
