TMS320F28035: TMS320F28035: Please Explain Comparator Behavior

Part Number: TMS320F28035


I am developing a dual active bridge converter, which is very similar in operation to a phase shift full bridge converter.  I am implementing peak current mode control using comparator 2.  

In the plot below, Channel 3 (magenta trace) is the comparator output, and Channel 4 (green trace) is the current feedback / comparator input.

Note that the rising edge of the comparator triggers at approximately 3.02 Volts, and the falling edge releases at approximately 720mV.  I would expect the edges to rise and fall at about the same magnitude, with the hysteresis.  Can somebody please explain this behavior?

Thanks in advance for any assistance.
