High-End Timer (N2HET) Module
23.3.2.4 Hardware Angle Generator and High-End Timer
In the engine management application, the HWAG is usually connected to one or more high-end timers.
This connection allows you to perform angle compare and angle/time compare. For an example of the
hardware angle generator/high-end timer interface, see Figure 23-50.

23.3.2.4.1 Signal Description
To perform a resynchronization, the HWAG interface provides to the NHET at every resolution clock an
angle increment value that represents how much the angle counter of the HWAG has been incremented
since the last NHET resolution clock. For an example of the angle count within the HWAG, see Figure 23-
51.
