1.15 MCRAMC ECC with Fault Injection Testing

This example application demonstrates how to test the SRAM using the MCRAMC ECC feature on internal SRAM memory.

Description

This example uses the MCRAMC to test its ECC with Fault Injection feature. This application writes a 32-bit data in SRAM for single and double error injection to highlight SEC and DED process.
