Attributes
TRCCIDR0 is a 32-bit register.
Field descriptions
The TRCCIDR0 bit assignments are:
Bits [31:8]
Reserved, RES0.
PRMBL_0, bits [7:0]
Component identification preamble, segment 0.

Accessing the TRCCIDR0
External debugger accesses to this register are unaffected by the OS Lock.
TRCCIDR0 can be accessed through the external debug interface:
| Component | Offset |
