14.7.5 Management Control to Host Register - MANC2H
(5860h; R/W)
The MANC2H register enables the routing of manageability packets to the host based on the decision
filter that routed it to the manageability micro-controller. Each manageability decision filter (MDEF) has
a corresponding bit in the MANC2H register. When a manageability decision filter (MDEF) routes a
packet to manageability, it also routes the packet to the host if the corresponding MANC2HOST bit is set
and if the EN_MNG2HOST bit is set. The EN_MNG2HOST bit serves as a global enable for the MANC2H
bits.
Reset - The MANC2H register is cleared on an Internal_Power_On_Reset and a firmware reset. The
initial values for this register can be loaded from the EEPROM after an Internal Power On Rest or
firmware reset.
