The external master performs Byte Read commands to the Intel
Slave I/F. The “Command” field (bits 11-18) indicate which register is being accessed.
The Data field (bits 30-37) contains the value that should be read from that register.

Description
Reserved
SMLINK_SLV_SMI. When Intel
in the S0 state, it sets the SMLINK_SLV_SMI_STS bit (see
“TCO1_CNT—TCO1 Control
the system is in an S0 state. When the message is received during S1-S5 states,
the Intel
does not get set.
NOTE: It is possible that the system transitions out of the S0 state at the same
Reserved
time that the SMLINK_SLV_SMI command is received. In this case, the
SMLINK_SLV_SMI_STS bit may get set but not serviced before the
system goes to sleep. Once the system returns to S0, the SMI associated
with this bit would then be generated. Software must be able to handle
this scenario.
