TMS320F28069：Ramp Generator：Can TMS320F28069 modify the slope value through the Ramp Generator？

I am working on the COT control in the Buck circuit, considering the Ramp Generator in the comparator module in the TMS320F28069 to generate the slope compensation signal.

See in the Q&A below:

e2e.ti.com/…/639644

"Datasheet says the reference 12-bit DAC uses the most significant 12 bits of the RAMPSTS countdown register as its input.The low 4 bits of the RAMPSTS countdown register effective act as a prescale for the falling-ramp rate configurable with RAMPDECVALA."

In this case,the lower 4 bits of the RAMPSTS register can be used to modify the slope value. However, I have not found this in the user manual of TMS320F28069.

Now I want to ask the following questions:

1. Can TMS320F28069 modify the slope value through the above registers?

2. How is the slope value range calculated?
