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.
