Software start up, optimisation for automotive MCU

This application note describes a recommended software start up procedure for the MPC5744P 32bit Power Architecture automotive microcontroller. This covers starting the Power Architecture core, memory protection unit (MPU), clock frequency (PLL), watchdog timer, flash memory controller, and internal static RAM. Recommended configuration settings for these modules will be given for the purpose of optimising system performance.

The MPC5744P is a 32bit Power Architecture Microcontroller that targets chassis and safety applications and other applications requiring a high Automotive Safety Integrity Level (SIL).
