Control Expert-How to implement the tracking function of RAMP DFB
1. Issue

As we set “EN” pin to True, Ramp starts incrementing or decrementing the value based on the logic.

However when “EN’ pin is set to False, Ramp function keeps incrementing or decrementing the value internally and externally on the output it holds the last value.

Later, when we set “EN” pin back to True, instead of starting from the last value it pushes the internal value it incremented or decremented until the Ramp function was disable.

2. Product Line
ECE V15.0

3. Environment
Win10 Pro 64Bit, ECE V14.0/V14.1

4. Resolution
This block has no such tracking function by default. You need to set TR_S=1 to active tracking mode.
Here is an example for customer's request. Please check the snapshot for reference.

When the EN_RAMP goes to 1, the SP will start from the last value. The internal value will be ignored.
