3.16.17. Counter Reload Event Registers, ETMCNTRLDEVRn

The ETMCNTRLDEVR characteristics are:

Purpose

An ETMCNTRLDEVR defines the event that causes the corresponding counter to be reloaded with the value held in the corresponding ETMCNTRLDVR.

Usage constraints

Each ETMCNTRLDEVR is used with a corresponding ETMCNTRLDVR, ETMCNTENR, and ETMCNTVR. See About the counter registers.

Configurations

The number of ETMCNTRLDEVRs:

  • is implementation defined

  • is specified by ETMCCR bits [15:13]

  • can be zero.

See Configuration Code Register, ETMCCR.

Unimplemented ETMCNTRLDEVRs are RAZ/WI.

Attributes

See the register summary in Table 3.16.

Figure 3.26 shows the ETMCNTRLDEVR bit assignments.

Bits

Description

[31:17]Reserved

[16:0]

Count reload 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 ETMCNTRLDEVR has the same bit assignments.

Defining a PTM event describes how you define a counter reload event.
