1.7 Using the MPC5604B
There are many different approaches to designing a system using the MPC5604B so the guidance in this
section is provided as an example of how the documents can be applied in this task.
Familiarity with the MPC5604B modules can help ensure that its features are being optimally used in a
system design. Therefore, the current chapter is a good starting point. Further information on the detailed
features of a module are provided within the module chapters. These, combined with the current chapter,
should provide a good introduction to the functions available on the MCU.
1.7.1 Hardware design
The MPC5604B requires that certain pins are connected to particular power supplies, system functions and
other voltage levels for operation.
