TMS320F280037C: Interrupt flag didn't appear in PIE ctrl registers and didn't trigger interrupt

Part Number: TMS320F280037C
Other Parts Discussed in Thread: SYSCONFIG, TMS320F28377D

Hello team, 

I have a problem with interrupts from Sigma Delta Filter Module. 

I have a configuration generated by SysConfig for SDFM and other peripherals that I use in my case. 

All signals are connected and tested in hardware and the module returns correct data in appropriate intervals. 

The problem appears when I want to trigger the interrupt from the New data filter acknowledgment event. 

In module registers flags are present. I receive 4 flags from AF and MIF. 

In PieCtrlRegs flags SDFM1 interrupt (5.9) and  SDFM1 interrupt (5.10) occurs but interrupts are not enabled for this events. 

I IER registers 5.13 (SDFM1DR1 interrupt) and 6.13 (SDFM2DR1 interrupt) are enabled and pointers to interrupts are assigned  correctly to vector table. 

Main problem is that AF1-AF4 events didn't trigger interrupt in interrupt module even if they accurs in SDFM module. 

I checked another interrupts i.e. EPwm interrupts and this interrupt is working and module handle interrupt correctly, receive interrupt flag and jump to approriate function in vector table. 

Also, I checked the identical configuration in another microcontroller (TMS320F28377D) and interrupts are triggered correctly. I receive all frags AF and MIF also in that case. 

I wonder if this is a hardware problem in this MCU or if I missed something in the configuration process.
