3.5.29. Counter Reload Event Registers, ETMCNTRLDEVRn

The ETMCNTRLDEVR characteristics are:

Purpose

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 3.3, and Reset behavior.
