3.4.6. 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-R7.

Usage constraints

There are no usage constraints.

Configurations

Available in all configurations.

Attributes

See the register summary in Table 3.1 and Table 3.2.

BitsNameFunction
[31]TYPE3

Selects the resource type for event 3:

0

Single selected resource.

1

Boolean combined resource pair.

[30:28]-RAZ/WI
[27:24]SEL3

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].

[23]TYPE2

Selects the resource type for event 2:

0

Single selected resource.

1

Boolean combined resource pair.

[22:20]-RAZ/WI
[19:16]SEL2

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].

[15]TYPE1

Selects the resource type for event 1:

0

Single selected resource.

1

Boolean combined resource pair.

[14:12]-RAZ/WI
[11:8]SEL1

Selects the resource number, based on the value of TYPE1:

When TYPE1 is 0, selects a single selected resource from 0-15 defined by bits[3:0].

When TYPE1 is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].

[7]TYPE0

Selects the resource type for event 0:

0

Single selected resource.

1

Boolean combined resource pair.

[6:4]-RAZ/WI
[3:0]SEL0

Selects the resource number, based on the value of TYPE0:

When TYPE0 is 0, selects a single selected resource from 0-15 defined by bits[3:0].

When TYPE0 is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].
