Detailed Description

Structure to store essential, mutable SCB register values for backup/restore.

This structure only contains SCB registers that are safe and meaningful to backup and restore. In particular, registers that are read-only (such as CPUID) or contain volatile information (ICSR / CFSR) are ignored, since their value is tied to the system state or fixed in hardware, rather than related to a configuration option.
