ARM Cortex-A35 User Manual

C11.7 Event Control 0 Register
The TRCEVENTCTL0R characteristics are:
Purpose
Controls the tracing of events in the trace stream. The events also drive the external outputs
from the ETM trace unit. The events are selected from the Resource Selectors.
Usage constraints
• You must always program this register as part of trace unit initialization.
• Accepts writes only when the trace unit is disabled.
Configurations
Available in all configurations.
Attributes
See C11.1 ETM register summary on page C11-733.

TYPE3, [31]
Selects the resource type for trace event 3:
0 Single selected resource.
1 Boolean combined resource pair.
[30:28]
Reserved, RES0.
SEL3, [27:24]
Selects the resource number, based on the value of TYPE3:
When TYPE3 is 0, selects a single selected resource from 0-15 defined by bits[3:0].
When TYPE3 is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].
TYPE2, [23]
Selects the resource type for trace event 2:
0 Single selected resource.
1 Boolean combined resource pair.
[22:20]
Reserved, RES0.
SEL2, [19:16]
Selects the resource number, based on the value of TYPE2:
When TYPE2 is 0, selects a single selected resource from 0-15 defined by bits[3:0].
When TYPE2 is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].
TYPE1, [15]
Selects the resource type for trace event 1:
0 Single selected resource.
