Event Type Configuration Registers, GICP_EVTYPERn

These registers configure which events are counted by the event counter n. The GIC-600 supports five counters, n = 0-4.

The GICP_EVTYPERn characteristics are:

Usage constraintsThere are no usage constraints.
ConfigurationsAvailable in all GIC-600 configurations.
AttributesSee GICP register summary.

The following figure shows the bit assignments.

Figure 4-44 GICP_EVTYPERn bit assignments

The following table shows the bit assignments.

Table 4-59 GICP_EVTYPERn bit assignments

Bits Name Function

When set to 1, an overflow of counter n triggers a capture if GICP_CAPR.CAPTURE is set.

[30:18] - Reserved.
[17:16] EVENT_TYPE

Event tracking type:

0b00 = Count events.

0b10 = MaximumEvent.

0b11 = Reserved.

[15:8] - Reserved.
[7:0] EVENT

Event identifier.

All events reset to an unknown value.

Registers corresponding to unimplemented counters are RES0.

See Table   4-60 EVENT field encoding.

The following table shows the events that the GIC can count.
