Chapter 9. Interrupt Control and System Control
Overview of the NVIC and System Control Block Features
The Nested Vectored Interrupt Controller (NVIC) is an integrated part of the Cortex-M0 processor. It is closely linked to the processor core logic and provides the functions of interrupt control and system exception support.
Apart from the NVIC, there is also a System Control Block (SCB), which shares the same System Control Space (SCS) memory address range. The SCB contains features for operating system support, like an internal timer for the SysTick exception. The OS-related features will be covered in Chapter 10.
The NVIC features were explored in Chapter 3. Those features include the following:
• Flexible interrupt management include enable/disable, ...
