TMS320F280049: Question about pfc1ph3ilttpl_nonpowerSUITE_F28004x

Genius 3095 points
Part Number: TMS320F280049


Dear team:

I am using the pfc1ph3ilttpl_nonpowerSUITE_F28004x (c2000\C2000Ware_DigitalPower_SDK_2_00_01_00\solutions\tidm_1007) for my test, and set the below two function as:

INCR_BUILD = 1 //open loop

DC_CHECK = 1 //Fixed duty cycle

After power-on, I can see that GPIO16 can output 100KHz waveform, But when I check the PWM2A, PWM3A, PWM4A, They have to be delayed for 30 seconds before they have output. But according to the code in controlisr(), there should be output when power is on. 

Is my experiment correct?
