The TRCVDCTLR characteristics are:

Purpose

Controls data trace filtering.

Usage constraints

Can only be written when the ETM-R7 is disabled.

Configurations

Available in all configurations.

Attributes

See the register summary in Table 3.1 and Table 3.3.

BitsNameFunction
[31:11]-RAZ/WI
[10]PCREL

Controls tracing of data for transfers that are relative to the Program Counter (PC):

0

Tracing of PC-relative transfers is unaffected.

1

Do not trace either the address or value portions of PC-relative transfers.

[9:8]SPREL

Controls tracing of data for transfers that are relative to the Stack Pointer (SP):

b00

Tracing of SP-relative transfers is unaffected.

b01

Reserved.

b10

Do not trace the address portion of SP-relative transfers. A P1 data address element is generated if data value tracing is enabled.

b11

Do not trace either the address or value portions of SP-relative transfers.

[7]TYPE

Selects the resource type:

0

Single selected resource.

1

Boolean combined resource pair.

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

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

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

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