PHY Address.
The PHY Address is used for the SMI address and for
the initialization of the Cipher (Scrambler) key. Refer
to
PHYAD[4:0]," on page 54
100Base-TX receiver-based error register that
increments when an invalid code symbol is received
including IDLE symbols. The counter is incremented
only once per packet, even when the received packet
contains more than one symbol error. The 16-bit
register counts up to 65,536 (2
if incremented beyond that value. This register is
cleared on reset, but is not cleared by reading the
register. It does not increment in 10Base-T mode.
Write as 0, ignore on read.
Alternate Interrupt Mode.
0 = Primary interrupt system enabled (Default).
1 = Alternate interrupt system enabled.
See
Write as 0, ignore on read.
1 = PHY disregards PHY address in SMI access
0 = normal operation;
1 = force 100TX- link active;
Note:
ENERGYON – indicates whether energy is detected
on the line (see
Power-Down," on page
energy is detected within 256ms. Reset to “1” by
hardware reset, unaffected by SW reset.
Write as 0, ignore on read.
