Setting this bit clears the no_lnk_int interrupt.
Setting this bit clears the jabber_cng_int interrupt.
Setting this bit clears the nxt_pg_rcvd_int interrupt.
Setting this bit clears the an_cmpl_int interrupt.
Setting this bit clears the rem_flt_cng_int interrupt.
Write as 0, ignore on read.
BIST Counter: This register counts receive packets or receive
errors according to bit 15 in register BIST_CFG1. It shows either
the upper or lower 16 bit of a 32 bit value which can be selected
through bit 14 in register BIST_CFG2.
Set BIST Counter Type:
1 = BIST_CNT counts receive CRC errors
0 = BIST_CNT counts receive packets
BIST Counter Clear: Setting this bit clears the BIST_CNT regis-
ter to 0.
Transmit BIST Packet Length:
1 = 1514 bytes
0 = 60 bytes
Transmit BIST Interframe Gap: This bit sets the IFG for transmit
BIST packets.
1 = 9.6 us
0 = 0.096us
Transmit BIST Enable: This bit starts the transmit BIST. The
number of selected packets or a continous data stream is sent out
when set. This bit self-clears after the packets have been sent.
1 = Transmit BIST enabled
0 = Transmit BIST disabled
