GLIU Register Descriptions (Continued)

5.1.1.3

GeodeLink Device SMI MSR (GLIU_GLD_MSR_SMI)

The flags are set by internal conditions. The internal conditions are enabled if the EN bit is 0. Reading the FLAG bit returns

the value; writing 1 clears the flag; writing 0 has no effect. (See Section 3.8.3 "MSR Address 2: SMI Control" on page 67 for

further SMI and ASMI generation details.)

STATCNT2_

ASMI_FLAG

Statistic Counter 2 ASMI Flag. If high, records that an ASMI was generated due to a

Statistic Counter 2 (MSR 510100A8h) event. Write 1 to clear; writing 0 has no effect.

STATCNT2_ASMI_EN (bit 3) must be low to generate ASMI and set flag.

STATCNT1_

ASMI_FLAG

Statistic Counter 1 ASMI Flag. If high, records that an ASMI was generated due to a

Statistic Counter 1 (MSR 510100A4h) event. Write 1 to clear; writing 0 has no effect.

STATCNT1_ASMI_EN (bit 2) must be low to generate ASMI and set flag.

STATCNT0_

ASMI_FLAG

Statistic Counter 0 SMI Flag. If high, records that an ASMI was generated due to a Sta-

tistic Counter 0 (MSR 510100A0h) event. Write 1 to clear; writing 0 has no effect.

STATCNT0_ASMI_EN (bit 1) must be low to generate ASMI and set flag.

SSMI_FLAG

SSMI Flag. If high, records that an SSMI was generated due to a received event. Event

sources are:

• Illegal request type to GLIU (Port 0), meaning anything other than MSR read/write,

debug request, and null.

• A self-referencing packet (i.e., a packet sent to the GLIU that finds its destination port

is the source port).

• The destination of the packet is to a port where the GLIU slave for that port has been

disabled.

• Trap on a descriptor with device port set to 0. This is the typical operational use of this

bit. The data returned with such a trap is the value 0.

Write 1 to clear; writing 0 has no effect. SSMI_EN (bit 0) must be low to generate SSMI

and set flag.
