C64X+ Memory protection question

Anonymous

Hi All,

I was reading a post relating C64x+ memory protection:

Brad Griffis said:

Sorry, but these features are not supported on the DM6437. This is documented in the DM643x DSP Subsystem Guide.

Section 2.3.1:

The DM643x DMP does not support the L1P memory protection feature of the standard
C64x+ Megamodule.

Section 2.3.2:

The DM643x DMP does not support the L1D memory protection features of the standard
C64x+ Megamodule.

Section 2.3.3:

The DM643x DMP does not support the L2 memory protection feature of the standard
C64x+ Megamodule.

 

But why in configuring the RTSC platform I was still able to edit their access properties?

 

They are intially gray, what does that gray mean?

 

 

 

Sincerely,

Zheng
