Cyclone V: How can i set the debug authentication signals DBGEN and SPIDEN etc.?

Hello,

I am using a Cyclone V SoC with Cortex-A9 MPCore.

The ARM Architecture TRM and Cortex-A9 TRM say that an external security controller drives the debug authentication signals, such as DBGEN and SPIDEN.

I found no information whatsoever on how to drive these signals.
Are these even publicly documented? How can I access and set these debug authentication signals?

Kind regards

Hi,

Let me check with our internal team regarding the authentication status register mentioned.

Thanks.

Hi,

These registers and signals in CortexA9 core.
Usually we refer user to the ARM documentation.
