Crank angle  domain is far superior to PMM.  I believe TPU mask G has it.  No more free running counter error if the time between sparks ( rate of crankshaft) changes.

Hello list,

I just stumbled onto this app note about the angle clock. It appears the
angle clock might make tracking crankshaft angle easier (less complexity)
than using PMM/PMMX. What do you think?

I've been trying to figure out how to track the 24X trigger wheel in my LS1
engine, this might make it a manageable task.

Regards,

Dave

Dave,
Looks like a nice function. Its more capable than PMM but I'm not sure I would say its any less complex.

If Freescale ever releases the automotive functions for the eTPU to general distribution they might be worth a look. Are you working with an eTPU micro ?
