• Nested Vectored Interrupt Controller (NVIC)
• System Control Block (SCB)
• System Timer (SysTick)
• Memory Protection Unit (MPU)
• the required privilege gives the privilege level required to access the register, as follows:
The Nested Vectored Interrupt Controller (NVIC) is an embedded interrupt controller that
supports low latency interrupt processing. See
Controller (NVIC)”
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. See
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. See
(SysTick)”
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. See
– Privileged: Only privileged software can access the register.
– Unprivileged: Both unprivileged and privileged software can access the register.
