The TRCPIDR4 characteristics are:
- Provides information to identify a trace component.
- Usage constraints
- Only bits[7:0] are valid.
- Accessible only from the memory-mapped interface or the external
- Available in all implementations.
A 32-bit RO management register.

|Size of the component. Log2 the number of 4KB pages from the
start of the component to the end of the ETM component ID registers.
|ARM Limited. This is the least significant nibble of the
JEP106 continuation code.
TRCPIDR4 can be accessed through the internal memory-mapped interface and
the external debug interface, offset
