Section 8. Interrupts - Microchip Technology
ww1.microchip.comGenerally the interrupt flag bit(s) must be cleared in software before re-enabling the global inter-rupt to avoid recursive interrupts. Once in the interrupt service routine the source(s) of the interrupt can be determined by polling the interrupt flag bits. Individual interrupt flag bits are set regardless of the status of their
Measuring Interrupt Latency - NXP
www.nxp.comof an Interrupt Request (IRQ) and the start of the respective Interrupt Service Routine (ISR). The interrupt latency is expressed in core clock cycles. 5.There is another exact definition-the number of clock cycles from the assertion of the interrupt request to the first ISR instruction executed, as shown in Figure 6.1. Conclusion

Interrupts C - Uppsala University
www.signal.uu.seC.4 FEATURES OF INTERRUPT SERVICE ROUTINES An interrupt service routine (ISR) is a special routine that is executed outside of the normal program flow. An ISR is invoked in response to a particular interrupt occurring at an undetermined time. Since an interrupt occurs at an unknown time, it cannot return a value directly to a program.
LTC2954 Pushbutton On/Off Controller with µP Interrupt ...
www.analog.comController with µP Interrupt The LTC®2954 is a pushbutton on/off controller that manages system power via a pushbutton interface. An enable output toggles system power while an interrupt output provides debounced pushbutton status. The inter-rupt output can be used in menu driven applications to request a system power-down. A power kill input ...

The computer's BIOS (Basic Input Output System) contains a software routine that counts the interrupt requests and generates a time-of-day clock that can Computer Time Synchronization Michael Lombardi Time and Frequency Division
