1. The startup on communication line wakes the CPU which was made possible by an EXTI, this induces a delay before

entering run mode.

ARM® Cortex®-M3 core with MPU

The ARM® Cortex®-M3 processor is the industry leading processor for embedded systems.

It has been developed to provide a low-cost platform that meets the needs of MCU

implementation, with a reduced pin count and low-power consumption, while delivering

outstanding computational performance and an advanced system response to interrupts.

The ARM® Cortex®-M3 32-bit RISC processor features exceptional code-efficiency,

delivering the high-performance expected from an ARM core in the memory size usually

associated with 8- and 16-bit devices.

The memory protection unit (MPU) improves system reliability by defining the memory

attributes (such as read/write access permissions) for different memory regions. It provides

up to eight different regions and an optional predefined background region.

Owing to its embedded ARM core, the STM32L151x6/8/B and STM32L152x6/8/B devices

are compatible with all ARM tools and software.
