Description
test mode only - do not set high
1 indicates polarity reversal on RX inputs (10Base-T)
copy of PHY address pins
1 = aneg completed
0 = aneg did not complete (same as reg1.5)
ANEG result - duplex operation
0 = HDX, 1 = FDX
ANEG result - speed of operation
0 = 10M, 1 = 100M
1 = abilities match between registers 4 & 5
ANEG state machine current state
Description
number of RX_ERR events since last read - Clears
either in change of speed or read of this reg.
Description
the disconnect mechanism status
number of False CRS events since last read.
Active only when DISCEN = 1”.
