Page 26: Recognize Different Interrupt Service Requests
2.2.2. Recognize different interrupt service requests I-9048 / I-8048W is an 8 channels rising/falling edge programmable interrupt module. It can plug into slot of the PAC controllers. The section introduces how to recognize interrupt requests from different slots and channels. I-9048/I-8048W Linux API Reference, v 1.0.2 E-mail: service@icpdas.com... - Page 27 Requests from different slots Each slot is assigned an interrupt pin of the CPU shown in section 1.3. So their ISTs are different. CPU executes different ISR when the request is from different slot. Considering when the interrupts occur, the situations can be divided to two kinds. Interrupted at different time CPU executes ISTs one by one in the order of when they occurred.
