Lizard Labs is a new online training program provided by Energy Micro. The purpose of Lizard Labs is for EFM32 users to get started with EFM32 microcontrollers and learn about some of the main EFM32 features that the users can take advantage of. Each training module covers a specific topic, and the modules are divided into levels. A higher level module may assume that the viewer is already familiar with the topics in the lower levels. Visit our Lizard Labs page for more information.
This lecture will explain how interrupts and energy modes work on the EFM32. You will learn how to write code that enables and executes interrupt service routines. You will also learn about interrupt priority, tailchaining and late arrival which are features of the Cortex-M3 interrupts that help reduce interrupt latency. You will learn the difference between the EFM32 energy modes and how to transition between them.
