12.7.1 Peripherals
Nested Vectored Interrupt Controller (NVIC)
The Nested Vectored Interrupt Controller (NVIC) is an embedded interrupt controller that supports low
latency interrupt processing. See
System Control Block (SCB)
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
System Timer (SysTick)
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
Memory Protection Unit (MPU)
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.

Address Map
The address map of the Private peripheral bus (PPB) is:
In register descriptions:
The required privilege gives the privilege level required to access the register, as follows:
̶
Privileged: Only privileged software can access the register.
̶
Unprivileged: Both unprivileged and privileged software can access the register.
