3.16.25. Context ID Comparator Mask Register, ETMCIDCMR

The ETMCIDCMR characteristics are:

Purpose

Holds a 32-bit mask for use for all Context ID comparisons.

Usage constraints

There are no usage constraints.

Configurations

The number of Context ID comparators:

  • is implementation defined

  • is specified by ETMCCR bits [25:24]

  • can be zero.

See Configuration Code Register, ETMCCR.

If the PTM does not implement any Context ID comparators then the ETMCIDCMR is RAZ/WI.

Attributes

See the register summary in Table 3.16.

Description

Context ID mask value


The same mask is used for all of the Context ID comparators. When a Context ID mask bit is set to 1, the corresponding bit in the Value Register is disregarded in the comparison and should be zero.
