TMS320F280049C: When Use the Adca interrupt, the interrupt flag has all setted in the ADC register and PIE register. But it can't propagation to the CPU register.

Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE

as described in the title, I can't trig adca interrupt. the register value of ADCA stage/PIE stage/CPU stage is shown below.

can anyone point out some directions that may has some problem.

from left to right, it is CPU stage registers and its value/ADCA stage registers and its value/PIE stage registers and its value

There are interrupt-based examples in C2000ware (C:\ti\c2000\C2000Ware_5_01_00_00\driverlib\f28004x\examples\adc). These are tested examples. Please compare your code with these examples for interrupt initialization.

this problem has been solved. after I set INTxCONT bit in the ADCINTSEL1N2 register. Then the DSP can run into Adca interrupt.

which means it is the same problem as TMS320F280049: ADC interrupt problem - C2000 microcontrollers forum - C2000︎ microcontrollers - TI E2E support forums
