TMS320F280039C: about HIC/DMA Write/Read non-master access violation in mem

The relevant registers are defined in 3.15.2.1 and 3.15.2.2 in the TMS320F28003x Real-Time Microcontrollers documentation, but there is no specific implementation method in 3.11.7.7 and 3.11.7.8.

In the related routine, I found that your company implements non master access violation via the NMAVSET.DMAWRITE=1 field in force 3.15.2.2.

Pls are the following 4 functions implemented in 280039C?

non-master DMA write violation；

non-master DMA read violation；

non-master HIC write violation；

non-master HIC read violation；

I have already transferred your issue to the relevant engineer, pls focus on the link below:

Please have a look at the MemCfg_enableViolationInterrupt and MemCfg_disableViolationInterrupt function in the memcfg module in driverlib function which is used to enable/disable the individual RAM access violation interrupt sources.

You can pass the bit mask of the interrupt sources to be enabled/disabled.

Let me know if you were asking the same.

I think you are referring to old TRM for the section numbers. Please take a look at the latest TRM.
