3.5.34. External Output Event Registers, ETMEXTOUTEVRn

The ETMEXTOUTEVR characteristics are:

Purpose

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 3.3, and Reset behavior.
