I have a piece of interrupt driven code which measures pulse width on both
ports (two channel ADXL202 digital pwm output). CCP1 is first set to rising
edge, inside of the hit interrupt, it is switched to falling edge, next
interrupt CCP2 is selected on rising and last one on CCP2 falling edge. The
pulses aren't that fast, but luckily I could regulate the average and
maximum pulse width so it's all covered withing one overflow of timer1 so I
don't have to do any fancy checking. Wasn't even that hard to set up.

Hey yeah - plus if the trigger edges were selectable it would be
great for measuring pulse widths. eg:

After enable,
1st trigger (+ve edge): reset TMR1
2nd trigger (-ve edge): capture, flag and disable.
