Can I have a negative input voltage in a comparator pin of MC56F82748?

Hi guys,

 

I just want to ask if the negative voltage(part of the square waveform) is acceptable to the pin of the comparator inside the DSP (MC56F82748VLH). If yes, is there any effect on having a negative voltage input? Do the comparator would reset through time because of this negative voltage?

 

Thank you
