1 = fault detected by parallel detection logic
0 = no fault detected by parallel detection logic
1 = link partner has next page ability
0 = link partner does not have next page ability
1 = local device has next page ability
0 = local device does not have next page ability
1 = new page received
0 = new page not yet received
1 = link partner has auto-negotiation ability

Four-bit silicon revision identifier.
Write as 0; ignore on read.
Enable the Energy Detect Power-Down mode:
0 = Energy Detect Power-Down is disabled
1 = Energy Detect Power-Down is enabled
Write as 0, ignore on read
The Low_Squelch signal is equal to LOWSQEN AND
EDPWRDOWN.
Low_Squelch = 1 implies a lower threshold
Low_Squelch = 0 implies a higher threshold
Management Data Preamble Bypass:
0 – detect SMI packets with Preamble
1 – detect SMI packets without preamble
Force the module to the FAR Loop Back mode, i.e. all
the received packets are sent back simultaneously (in
100Base-TX only). This bit is only active in RMII
mode. In this mode the user needs to supply a 50MHz
clock to the PHY. This mode works even if MII Isolate
(0.10) is set.
±15kV ESD Protected MII/RMII 10/100 Ethernet Transceiver with HP Auto-MDIX Support and flexPWR
