SPNU517A.pdf, page 594 notes: 17.3 Angle Functions Engine management systems require an angle-referenced time base to synchronize signals to the engine toothed wheel. The N2HET has a method to provide such a time base for low-end engine systems. The reference is created by the N2HET using three dedicated instructions with fractional angle steps equal to /8, /16, /32, /64. Trying to wrap my head around this. They say "low-end" systems. What is "low end"? Can I spin my 32 tooth wheel to 11000 RPM and get an accurate 'angle' from this? This is going to be fun. *note- thread / topic title changed.
