EXTERN void changeSyncStatus

(

unsigned char

)

Change the accumulator mode to overflow every 5 inputs on PT0 making our 360 tooth wheel interrupt like a 72 tooth wheel.

PT0 Accumulator Mode

Todo:

TODO Decide if an explicit parameter is necessary if not use a existing status var instead for now it's explicit.

Todo:

TODO the register below does not exist and I couldn't figure out what you meant to do...
