9.1.3. System Control Space

The processor provides debug through registers in the SCS. See:

SCS CoreSight identification

Table 9.5 shows the SCS CoreSight identification registers and values for debugger detection. Final debugger identification of the Cortex-M7 processor is through the CPUID register in the SCS. See CPUID Base Register.
