TMS320F28035: How to interrupt an interrupt

Hi Ti Team.

Have a question. I have two interrupts in my project both are configured in PieVectTable.

One is ADCINT1 which is generated by ADC EOC signal.

Second is SCIRXINTA which is generated from SCI RX buffer.

My goal is to interrupt the second one (SCIRXINTA) if ADCINT1 is generated in case when both are generated at the same time. How to configure SCIRXINTA interrupt to have a ability to interrupt it.
