The ETMCIDR2 characteristics are:

Purpose

Holds byte 2 of the CoreSight preamble information.

Usage constraints

  • From PFTv1.1, accesses to this register from the coprocessor interface are unpredictable.

Configurations

Available in all PTM implementations.

Attributes

See the register summary in Table 3.16.
