This bit is OR’ed with bit 14 (Loopback) in the BMCR.
1 = 10 Mb/s Loopback is enabled
0 = 10 Mb/s Loopback is disabled
Normal Link Pulse Disable:
This bit is OR’ed with the MAC_FORCE_LINK_10 signal.
1 = Transmission of NLPs is disabled
0 = Transmission of NLPs is enabled
Force 10 Mb/s Good Link:
This bit is OR’ed with the MAC_FORCE_LINK_10 signal.
1 = Forced Good 10 Mb/s Link
0 = Normal Link Status
Force 10 Mb/s Polarity Correction:
1 = Force inverted polarity
0 = Normal polarity
10 Mb/s Polarity Status: RO/LH
This bit is a duplication of bit 12 in the PHYSTS register. Both bits will be cleared upon a read of
either register.
1 = Inverted Polarity detected
0 = Correct Polarity detected
Auto Polarity Detection & Correction Disable:
1 = Polarity Sense & Correction disabled
0 = Polarity Sense & Correction enabled
Reserved
This bit must be written as a one.
Heartbeat Disable: This bit only has influence in half-duplex 10 Mb/s mode.
1 = Heartbeat function disabled
0 = Heartbeat function enabled
When the device is operating at 100 Mb/s or configured for full duplex, this bit will be ignored - the
heartbeat function is disabled.
Jabber Disable:
1 = Jabber function disabled
0 = Jabber function enabled
Applicable only in 10BASE-T Full Duplex.
Access: Read Write
