Hi,

 

There exists many Unified Channel Mode of Operation such as Input period measurement, Quadrature decode
(for phase_A and phase_B encoders type) for MPC5553. 

 

What does exactly happen when any of these modes is selected?

 

Let's consider quadrature decode mode (for phase_A and phase_B encoders type).  I want to know what happens in background if I select this mode. What settings have been already made for this encoder type? Where can I get the software code used for its settings?  

 

I've referred MPC5553/MPC5554 Microcontroller Reference Manual to understand basics but not getting idea how it is implemented in firmware code. 

 

Thanks in advance.
