If all you have to do in C is give the function a specific name, then your project is using weak binding to select the interrupt handler. In this case, all you need to do is create an assembly function with the correct symbol name. With EABI, this should be the same as the C function name. bind8 download

WebAn interrupt service routine (ISR) is a software routine that hardware invokes in response to an interrupt. ISR examines an interrupt and determines how to handle it executes the handling, and then returns a logical interrupt value. If no further handling is required the ISR notifies the kernel with a return value.

The external pin interrupt is triggered whenever there is a "change of state" on the RB0/INT (pin #6 on the PIC16F84A). The change of state means the pin went from high to low or low to high. To enable this interrupt, you have to set the INTE (bit 4, External Interrupt Enable) bit of the INTCON register. bind7 windows10

WebThe Central Processing Unit (CPU) is the brain / heart of a computer as it executes instructions. Instructions are coded in a language called “assembly” which is the only one spoken by the CPU. INT is an assembly language instruction for x86 processors that generates a software interrupt. It takes the interrupt number formatted as a byte value. When written in assembly language, the instruction is written like this: INT X where X is the software interrupt that should be generated (0-255).
