COMP0, [3:0]
Controls the mask value that the trace unit applies to TRCVMIDCVR0. Each bit in this field
corresponds to a byte in TRCVMIDCVR0. When a bit is:
0 The trace unit includes the relevant byte in TRCVMIDCVR0 when it performs the
Virtual context ID comparison.
1 The trace unit ignores the relevant byte in TRCVMIDCVR0 when it performs the
Virtual context ID comparison.
Bit fields and details not provided in this description are architecturally defined. See the Arm
