instruction. In this case, the response time is 19 system clock cycles: 1 clock cycle to detect the interrupt,
5 clock cycles to execute the RETI, 8 clock cycles to complete the DIV instruction and 5 clock cycles to exe-
cute the LCALL to the ISR. If the CPU is executing an ISR for an interrupt with equal or higher priority, the
new interrupt will not be serviced until the current ISR completes, including the RETI and following instruc-
tion.
