The operational sequence from D0 to D3 should be:

Stop TX/RX process

wait for entering stop state

set

test mode, CR6<28:25> = 0011

programming FIFO

contents

exit test mode

enter D3 (hot) state

The sample frame data comparison is completed when the

received frame data has exceeded the programmed frame

length or when the whole packet has been fully received.

The operation procedure is shown below.
