3.16.22. External Output Event Registers, ETMEXTOUTEVRn

The ETMEXTOUTEVR characteristics are:

Purpose

An ETMEXTOUTEVR defines the event that controls the corresponding external output.

Usage constraints

There are no usage constraints.

Configurations

The number of external outputs:

  • is implementation defined

  • is specified by ETMCCR bits [22:20]

  • can be zero.

See Configuration Code Register, ETMCCR.

Unimplemented ETMEXTOUTEVRs are RAZ/WI.

Attributes

See the register summary in Table 3.16.

Figure 3.30 shows the ETMEXTOUTEVR bit assignments.

Bits

Description

[31:17]Reserved

[16:0]

External output event. Subdivided as:

Function, bits [16:14]

Specifies the logical operation that combines the two resources that define the event.

Resource B, bits [13:7] and Resource A, bits [6:0]

Specify the two resources that are combined by the logical operation specified by the Function field.

For more information see Event resources and PTM events.


Each ETMEXTOUTEVR has the same bit assignments.

Defining a PTM event describes how you define an external output event.
