TMS320F2800137: need help to understand instasipn solution

?? ???
Prodigy 10 points

Part Number: TMS320F2800137

Hello，team.

I am trying to understand the demo code of instaspin source code. 

So far, I have two questions:

Question 1: 

Why is there a #if defined(MOTOR1_FAST) && defined(MOTOR1_ESMO) // (OK<->OK) case in the isr program? Is it correct that if only the MOTOR1_FAST is defined in predefine, the code from line 1652 to line 2045 will be blocked?

Question 2: Can you explain the meaning of the following two define?#if !defined(_SIMPLE_FAST_LIB) && !defined(_HSWFREQ_EN)

    The project can support multiple estimator, and enable run the motor with FAST and eSMO at the same time.

    You may take a look at the lab user's guide for these definitions.

    It's only for test for the other projects, you can ignore these definitions.
