Cortex-M4 core peripherals

The peripherals are:

Nested vectored interrupt controller

The nested vectored interrupt controller (NVIC) is an embedded interrupt controller that

supports low latency interrupt processing.

System control block

The system control block (SCB) is the programmers model interface to the processor. It

provides system implementation information and system control, including

configuration, control, and reporting of system exceptions.

System timer

The system timer, SysTick, is a 24-bit count-down timer. Use this as a Real Time

Operating System (RTOS) tick timer or as a simple counter.

Memory protection unit

The Memory protection unit (MPU) improves system reliability by defining the memory

attributes for different memory regions. It provides up to eight different regions, and an

optional predefined background region.

Floating-point unit

The Floating-point unit (FPU) provides IEEE754-compliant operations on single-

precision, 32-bit, floating-point values.
