This might be a stupid question... but i'll ask anyways...

Does the external crystal for TMR1 have to be a crystal or is their other options?
For example, could i run it from one of the PWM lines... or perhaps an RC method... or some sort of TTL gates....

Also what about those ceramic resonators... they have 3 pins, how do you connect them? and can i use one on TMR1 (datasheet only briefly says to consult the manufacturers datasheet for caps with resonators, doesn't say you can use them)

Thanks
