6.7.2 Pass Through the LAN Configuration Modules (Global MNG
Offsets 0x05)
— The following sections describe pointers and structures dedicated to pass-through mode.
— These sections must be mapped in the non-protected area to enable an IT manager to change
it.
— These sections are available only in Legacy SMBus mode.

11 Multi-Drop NC-SI 1b
Multi-Drop NC-SI Topology.
0b = Point-to-point.
1b = Multi-drop (default).
When this bit is set, the NCSI_CRS_DV and NCSI_RXD[1:0] pins
are High-Z following power-up; otherwise, the pins are driven.
10 PARITY_ERR_RST_EN 1b
When set, enables reset of management logic and generation of
internal firmware reset as a result of parity error detected in
management memories.
9 Enable the PHY in D3 0b
0b = The PHY/SERDES behavior in D3 depends on the MNG mode:
In NC-SI mode - The PHY/SERDES can be deactivated in D3 if the
MC has issued a clear initial state command.
In SMBus mode – The PHY/SERDES will stay active in D3 when in
this mode.
1b = The PHY/SERDES stays active in D3.
