Note: FLX0-7 bits are set only when flex filter match is detected and WUFC.FLEX_HQ is 0b.
8.21.4 Wake Up Packet Length - WUPL (0x5900; RO)
This register indicates the length of the first wake-up packet received. It is valid if one of the bits in the
Wakeup Status register (WUS) is set. It is not cleared by any reset.
8.21.5 Wake Up Packet Memory - WUPM (0x5A00 + 4*n [n=0...31]; RO)
This register is read-only and it is used to store the first 128 bytes of the wake up packet for software
retrieval after system wake up. It is not cleared by any reset.
8.21.6 Proxying Filter Control Register - PROXYFC (0x5F60; R/W)
This register is used to enable each of the pre-defined and flexible filters for proxying support. A value
of 1b means the filter is turned on. A value of 0b means the filter is turned off.
If the NoTCO bit is set, then any packet that passes the manageability packet filtering, as described in
Section 10.3, is not forwarded to management (i.e. firmware) for protocol offload even if it passes one
of the proxying filters.

FW_RST_WK 31 0b
Wake Due to Firmware Reset Assertion Event.
When set to 1b, indicates that a firmware reset assertion caused the system wake so
that the software device driver can re-send proxying information to firmware.
Field Bit(s) Initial Value Description

than 2047 bytes then this field is 2047.)
