About this document

1.3.4

STM32L0 Cortex-M0+ core peripherals

These are:

Nested Vectored Interrupt Controller (NVIC)

The 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.

I/O port

The I/O port provides single-cycle loads and stores to tightly-coupled peripherals.
