8.2 CPU

The CPU subsystem (MCPUSS) implements an Arm Cortex-M0+ CPU, a system timer, and interrupt management features. The Arm Cortex-M0+ is a cost-optimized 32-bit CPU that delivers high performance and low power to embedded applications. Key features of the CPU Sub System include:

  • Arm Cortex-M0+ CPU supports clock frequencies from 32kHz to 32MHz
    • ARMv6-M Thumb instruction set (little endian) with 32-cycle 32x32 fast multiply instruction
  • Prefetch logic to improve sequential code execution, and I-cache with 2 64-bit cache lines
  • System timer (SysTick) with 24-bit down counter and automatic reload
  • Nested vectored interrupt controller (NVIC) with 4 programmable priority levels and tail chaining
