3.16.56. Peripheral ID2 Register, ETMPIDR2

The ETMPIDR2 characteristics are:


Holds peripheral identification information.

Usage constraints
  • Only bits [7:0] of this register are valid and they must be used with bits [7:0] of the other Peripheral ID registers to obtain the CoreSight Peripheral ID for the PTM.

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


Available in all PTM implementations.


See the register summary in Table 3.16.
