AUTOSAR Compendium
Part 2 – Basic Software & MCAL

The AUTOSAR Compendium – Part 2 covers the Basic Software & Microcontroller Abstraction Layer (MCAL) part of the AUTOSAR 4.2 specification. It explains the functionality of the Basic Software Modules and their configuration Parameters. The structure of the book corresponds to the Basic Software Layers and their functional Groups, down to the single Basic Software Modules:
