Reads as 0b0000.
Accessing the TRCCIDR1
External debugger accesses to this register are unaffected by the OS Lock.
TRCCIDR1 can be accessed through the external debug interface:
This interface is accessible as follows:
- When !IsTraceCorePowered() accesses to this register generate an error response.
- Otherwise accesses to this register are RO.
