WebThe device library provides a set of default interrupt routines, which will get used if you don't define your own. Patching into the vector table is only one part of the … WebInterrupts are signals provided to the CPU of the microcontroller unit, either from internal peripheral modules or from external pins of the MCU. It alters the regular flow of the program execution by enabling the CPU to make a jump to execute instruction routines in some pre-defined location based on the Webtions until the next Interrupt or Hardware Reset. In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleep-ing. The ADC Noise Reduction mode stops the CPU and all I/O modules except asynchronous timer and ADC, to minimize switching noise during ADC conversions. bitwit computer
