The System control block (SCB) provides system implementation information, and system con-
trol. This includes configuration, control, and reporting of the system exceptions. The system
control block registers are:
To improve software efficiency, the CMSIS simplifies the SCB register presentation. In the
CMSIS, the byte array SHP[0] to SHP[12] corresponds to the registers SHPR1-SHPR3.
