The Texas Instruments MSP430-series microcontrollers have I/O ports with configurable interrupt logic for each bit. You can select the rising or falling edge of the bit as the trigger. Even with the ...

Finally, on an AVR or MSP430, each possible interrupt has a fixed location in code memory where it goes to find an instruction to run when that interrupt is triggered.

Lesson 17 – How most CPUs (e.g., MSP430) handle interrupts. Function Calls are Synchronous. Each function call appears in the code explicitly, and the compiler generates specific machine instructions ...
