Diverse Integration Logic
5.6.1.4
Special cycles are sent to the Miscellaneous block. They
are decoded as given in Table 5-10. Note that the Halt spe-
cial cycle depends on the value of the SPEC_CYC_MD bit
in MSR_LEG_IO (MSR 51400014h[28]).
Soft IRQ and Soft Reset MSRs are decoded within the Mis-
cellaneous block.
Each block in the Diverse Device generates an output to
the DIVIL. The DIVIL DOM has a port for each of the func-
tions and is responsible for selecting between them.

Action
Send shutdown pulse to MSR_ERROR.
Send shutdown pulse to MSR_SMI.
If RESET_SHUT_EN (MSR 51400014h[31]) is high, send reset
pulse to power management indicating shutdown reset.
Send halt pulse to MSR_SMI.
Send halt pulse to MSR_SMI.
Discard with no side effects.
Discard with no side effects.
Send cycle to PIC.
GeodeLink Adapter generates back-to-back bus cycles.
Return zero with no side effects.
5.6.2
This block contains the Standard GeodeLink Device MSRs
and their associated logic. These standard MSRs are:
Capabilities, Master Configuration, SMI Control, Error Con-
trol, Power Management, and Diagnostics. The Capabili-
ties, Master Configuration, and Diagnostic MSRs are
“passive” in that they contain values that have an effect
elsewhere. The other MSRs have various “active” bits that
are set and cleared via hardware/software interactions.
