This is the quick start guide for the Integrity Check Monitor Controller (ICM), with step-by-step instructions on how to configure and use the driver for a specific use case.
The use cases contain several code fragments. The code fragments in the steps for setup can be copied into a custom initialization function, while the steps for usage can be copied into, e.g., the main application function.
Use cases
ICM basic usage
This use case will demonstrate how to configure and use of the on-chip ICM controller to check the integrity of internal SRAM. The region descriptor structure address in main list must be 64 byte alignment and in secondary list must be 4 byte alignment. The hash area start address must be 128 byte alignment. .*
