GLIU Register Descriptions (Continued)

RQCOMP_

ERR_FLAG

Request Comparator Error Flag. If high, records that an ERR was generated due to a

Request Comparator 0 (RQ_COMP_VAL, MSR 510100C0h) event. Write 1 to clear; writing

0 has no effect. RQCOMP_ERR_EN (bit 7) must be low to generate ERR and set flag.

RSVD

Reserved. Write as read.

STATCNT2_

ERR_FLAG

Statistic Counter 2 Error Flag. If high, records that an ERR was generated due to a Sta-

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

STATCNT2_ERR_EN (bit 5) must be low to generate ERR and set flag.

STATCNT1_

ERR_FLAG

Statistic Counter 1 Error Flag. If high, records that an ERR was generated due to a Sta-

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

STATCNT2_ERR_EN (bit 4) must be low to generate ERR and set flag.

STATCNT0_

ERR_FLAG

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

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

STATCNT0_ERR_EN (bit 3) must be low to generate ERR and set flag.

SSMI_ERR_

FLAG

SSMI Error Flag. If high, records that an ERR was generated due an unhandled SSMI

(synchronous error). Write 1 to clear; writing 0 has no effect. SSMI_ERR_EN (bit 2) must

be low to generate ERR and set flag. (Note 1)

UNEXP_ADD_

ERR_FLAG

Unexpected Address Error Flag. If high, records that an ERR was generated due an

unexpected address (synchronous error). Write 1 to clear; writing 0 has no effect.

UNEXP_ADD_ERR_EN (bit 1) must be low to generate ERR and set flag. (Note 1)

UNEXP_TYPE

_ERR_FLAG

Unexpected Type Error Flag. If high, records that an ERR was generated due an unex-

pected type (synchronous error). Write 1 to clear; writing 0 has no effect.

UNEXP_TYPE_ERR_EN (bit 0) must be low to generate ERR and set flag. (Note 1)

31:12

RSVD

Reserved. Write as read.

DACOMP_

ERR_EN

Data Comparator Error Enable. Write 0 to enable DACOMP_ERR_FLAG (bit 43) and to

allow a Data Comparator (DA_COMP_VAL_LO / DA_COMP_VAL_HI, MSR 510100D0h /

510100D1h) event to generate an ERR and set flag.

10:8

RSVD

Reserved. Write as read.

7RQCOMP_

ERR_EN

Request Comparator Error Enable. Write 0 to enable RQCOMP_ERR_FLAG (bit 39) and

to allow a Request Comparator (RQ_COMP_VAL, MSR 510100C0h) event to generate an

ERR.

RSVD

Reserved. Write as read.

STATCNT2_

ERR_EN

Statistic Counter 2 Error Enable. Write 0 to enable STATCNT2_ERR_FLAG (bit 37) and

to allow a Statistic Counter 2 (MSR 510100A8h) event to generate an ERR.

STATCNT1_

ERR_EN

Statistic Counter 1 Error Enable. Write 0 to enable STATCNT1_ERR_FLAG (bit 36) and

to allow a Statistic Counter 1 (MSR 510100A4h) event to generate an ERR.

STATCNT0_

ERR_EN

Statistic Counter 0 Error Enable. Write 0 to enable STATCNT0_ERR_FLAG (bit 35) and

to allow a Statistic Counter 0 (MSR 510100A0h) event to generate an ERR.

SSMI_ERR_

SSMI Error Enable. Write 0 to enable SSMI_ERR_FLAG (bit 34) and to allow the unhan-

dled SSMI (synchronous error) event to generate an ERR.

UNEXP_ADD_

ERR_EN

Unexpected Address Error Enable. Write 0 to enable UNEXP_ADD_ERR_FLAG (bit 33)

and to allow the unexpected address (synchronous error) event to generate an ERR.

UNEXP_TYPE

_ERR_EN

Unexpected Type Error Enable. Write 0 to enable UNEXP_TYPE_ERR_FLAG (bit 32)

and to allow the unexpected type (synchronous error) event to generate an ERR.

Note 1. These are synchronous errors, that is, they do not result in the assertion of the GL Error signal but instead set the

Exception bit in the response packet.
