RFS, Enables pause frame transmission based on occupied
received FIFO size
DEP1, Disables EP1 send 1-byte 00 function
EEP1, Enables EP1 send 1-byte 00 when more than frame_
interval’s NAK is received
, for more than 0 plus frame_interval ms NAK, EP1 sends 1-byte 00
, for more than 1 plus frame_interval ms NAK, EP1 sends 1-byte 00
, for more than 3 plus frame_interval ms NAK, EP1 sends 1-byte 00
