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. |
