Forum Post: TMS320F280036-Q1: In scenarios where software interrupt nesting is used, how to mask interrupts in the area of low-priority ISR sections

Part Number: TMS320F280036-Q1 Tool/software: hi，We used the software interrupt nesting feature on the F280036-Q1 chip. Now we want to mask the interrupt in a portion of the low-priority interrupt before turning on the For example, a priority A ISR can be nested into a lower priority ISR interrupt. If there is a critical program in the low-priority ISR service that needs to mask the interrupt of A, how should the code be modified Thanks
