TMS320F280039C: CLB_HLC_EVENT_SEL Register setting method

Part Number: TMS320F280039C

Hi expert,

I am debugging CLB example  clb_ex3_auxiliary_pwm

And I found it is not every time HLC have INTR instructor that run CLB ISR.

so I check the generated code, and found in clb_config.c

there is 

   CLB_configHLCEventSelect(base, TILE1_HLC_EVENT_SEL);

and in clb_config.h, there defines TILE1_HLC_EVENT_SEL 0x3

But I did not found where define this in our CLB tool?
