I need to use interrupt service in my application, but I don't know what control registers need to be configured, and how an interrupt service routine (ISR) gets invoked. Can you please take external interrupt INT2 as an example to show how to program an ISR? Thanks.

In a MPLAB project, how do I eliminate the startup function from the lib in order to use my own startup code? I tried to delete the Library Search Path from the project build option, which I thought was the way to exclude it, however, the execution still starts from the default startup, and my startup was not invoked.

I realized that the dsPIC has 30 MIPS speed, however, the datasheet also states that it accepts DC to 40 MHz external clock input. My question is, if we use 40 MHz external clock oscillator as clock input, what will the CPU speed be, 40 MIPS or 30 MIPS?

Microchip dsPIC30F4012 was chosen for our application. According to its reference design, we used 7.3728 MHz crystal to generate system clock 29.4912 MHz. I noticed that UART communication works reliably, while CAN communication does not. Can you explain why and advise any suggestion?
