IPC@CHIP® RTOS-PPC – API Documentation
This is for experts only.
The @CHIP-RTOS-PPC provides many API functions to access the hardware. Normally, the user should use these API functions and there should be no need for a direct access to the hardware resources. Just for the case that these @CHIP-RTOS-PPC API functions are insufficient or a API is missing, the CLIB provides a variable that can be used to access the MPC5200B processor MBAR registers directly from the application.
To gain access to the MBAR hardware resources, the user has to call RTX_MemWindow(). Here's an example:
Note: You can easily crash the entire system when your application has access to the MBAR area and any programming errors are present. There's also a risk to interfere with devices needed by the system.
