3.5.24. Data Comparator Value Registers, ETMDCVRn

The ETMDCVR characteristics are:

Purpose

Holds a 32-bit data value for comparison.

Usage constraints

Each ETMDCVR is used with the corresponding ETMDCMR. See Data Comparator Mask Registers, ETMDCMRn.

Configurations

  • The number of ETMDCVRs is implementation defined, and is specified by ETMCCR bits [12:8]. See Configuration Code Register, ETMCCR. From ETMv3.3 the number of ETMDCVRs can be zero.

  • Each ETMDCVR has the same bit assignments.

  • Unimplemented ETMDCVRs are RAZ/WI.

Attributes

See the register summary in Table 3.3, and Reset behavior.

Figure 3.24 shows the ETMDCVR bit assignments.
