3.16.25. Context ID Comparator Mask Register, ETMCIDCMR

The ETMCIDCMR characteristics are:


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

Usage constraints

There are no usage constraints.


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.


See the register summary in Table 3.16.

Figure 3.32 shows the ETMCIDCMR bit assignments.

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.
