TMS320C6748: ESD/Disable DLL Implementation

Part Number:TMS320C6748

Hi, 

As per the TMS320C6748 Errata, to aid with ESD issues we are experiencing.

We had our SW team try to implement the SW configuration to disable the DLL REFCLK for dynamic glitch tracking:

But now the C6748 is hung up, when trying to debug this code via the GEL file, we got the following error:

I imagine there is a step we are missing when setting the DRPYC1R register, we are running at 300MHz, vs the 150MHz in the example above, in which case I would expect we only need to wait half the time till setting this register.

I'm wondering if anyone else has encountered this issue? Or if anyone has a suggestion on how to set this register so we don't stall the whole processor?

I appreciate any help,
