It took some time to find the "feature" list you referenced, Its at the start of the Timer2 section. That seems to be the only place where "single channel" occurs in the whole document.

That timer has no input capture, but DOES have an external clock input. 

It IS able to provide a variable-frequency, variable-dutycycle PWM using the two compare modules, using one to control TOP. but Timer0 seems to be able to do that also.

Stumps me....
