DESCRIPTION
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
(more sensitive).
Low_Squelch = 0 implies a higher threshold
(less sensitive).
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, as described in Section 5.3.8.2. This mode
works even if MII Isolate (0.10) is set.
Write as 0, ignore on read.
