-/**
- * @file
- * @brief ARM CORTEX-M System Control Block interface
- *
- * Provide an interface to the System Control Block found on ARM Cortex-M
- * processors.
- *
- * The API does not account for all possible usages of the SCB, only the
- * functionalities needed by the kernel. It does not contain NVIC
- * functionalities either: these can be found in nvic.h. MPU functionalities
- * are not implemented.
- *
- * The same effect can be achieved by directly writing in the registers of the
- * SCB, with the layout available from scs.h, using the __scs.scb data
- * structure (or hardcoded values), but the APIs found here are less
- * error-prone, especially for registers with multiple instances to account
- * for 16 exceptions.
- *
- * If access to a missing functionality is needed, directly writing to the
- * registers is the way to implement it.
