Generally 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

Interrupt transfers control to the interrupt service routine generally, through the interrupt vector, which contains the addresses of all the service routines Interrupt architecture must save the address of the interrupted instruction Incoming interrupts are disabled while another interrupt is being processed to prevent a lost interruptnA

of 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.

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
