The TRCVMIDCCTLR0 is a 32-bit register.

Figure D10-72 TRCVMIDCCTLR0 bit assignments


RES0, [31:4]
res0Reserved.
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:

0The trace unit includes the relevant byte in TRCVMIDCVR0 when it performs the Virtual context ID comparison.
1The 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® Embedded Trace Macrocell Architecture Specification ETMv4.

The TRCVMIDCCTLR0 can be accessed through the external debug interface, offset 0x688.
