Help with Triggering exception( Data Storage ,WdT and Debug Interrupt ) for MPC5777C (e200z759CRM)

[Santhoshraj]

• I am working with the MPC5777C (e200z759CRM core) and trying to intentionally trigger a exception for testing purposes. However, instead of a DSI, I am encountering a Data TLB Exception
• I want to trigger DSI using one of the following conditions as per the PowerISA 2.06:

1. Read or Write Access Control Exception

2. Byte Ordering Exception

3. Cache Locking Exception

I attempted to generate a Read or Write Access Control Exception by writing to an invalid memory address, but it is causing a Data TLB Exception

I also need to trigger a Watchdog Timer Interrupt and Debug Interrupt Exception

I would appreciate any guidance on correctly triggering exceptions on the MPC5777C (e200z759CRM).

On this device ISI or DSI (IVOR2/3) may be caused by “Access control”. It means by restriction given by SMPU.
