ME SMBus Subsystem Vendor and Device ID
(MESMA2UDID):
MESMAUDID[15:0] - Subsystem Vendor ID
MESMAUDID[31:16] - Subsystem Device ID
The values contained in MESMAUDID[15:0] and
MESMAUDID[31:16] are provided as bytes 8-9 and 10-11 of
the data payload to an external master when it initiates a
Directed GET UDID Block Read Command to the Alert
Sending Device ASD's address.
This bit must only be set to ’1’ when there is an ASD
(Alert Sending Device) attached to SMBus and when
MESMASDEN(PCHSTRP2 bit 8) is set to ’1’. This is
only applicable in platforms using Intel
®
AMT. Set this
if you want to add a 4 byte payload to an external
master when a GET UDID Block read command is
made to Intel ME SMBus ASD’s address.
