TMS320F28035: Some questions about HVPSFB PCMC

Part Number: TMS320F28035

 

Hi Ti Experts,

For the PCMC mode of HVPSFB_v1.1, I would like to get your help on the following questions, thanks.

1. What is the role of the nops in HVPSFB-DPL-ISR.asm? Before and after these nops, the AQ control registers of SR are changed, what is the purpose of doing so?
2. Is there a maximum duty cycle (phase shift angle) limit in PCMC mode. The routine has the variable Dmax, is this variable used for the maximum duty cycle limit?
