If I use the Address check option available in the UART, the document says it transfers the FIFO.

   

Does this mean

   

1. Only the the 3 bytes left in the Hardware FIFO (one byte of address) is transferred? or

   

2. The rest of the message till data stops is transferred?

   

Thanks.

Just the other way round: You decide whether the address is put into the FIFO (and can be red by the code) or whether it is dropped and only the following bytes are captured.

Very much appreciate that response, but is just the FIFO's worth of data I will get or the RX buffer's worth?

The FIFO is part of the Rx buffer. Minimum buffer size is FIFO depth, maximum depends on ram available, transfer from FIFO to ram is done in an UART internal interrupt handler.
