Resets and Interrupts
5.5.1 Interrupt Recognition and Register Stacking
An interrupt can be recognized at any time after it is enabled by its local mask, if any, and by the global
mask bit in the CCR. Once an interrupt source is recognized, the CPU responds at the completion of the
instruction being executed. Interrupt latency varies according to the number of cycles required to
complete the current instruction. When the CPU begins to service an interrupt, the contents of the CPU
registers are pushed onto the stack in the order shown in
I bit and the X bit, if XIRQ is pending, are set to inhibit further interrupts. The interrupt vector for the highest
priority pending source is fetched and execution continues at the address specified by the vector. At the
