Delay from WR assertion to interrupt request deassertion for
level sensitive fast interrupts
Synchronous int setup time from IRQs NMI assertion to the
CLKOUT trans.
Synch. int delay time from the CLKOUT trans2 to the first
external address out valid caused by first inst fetch
Duration for IRQA assertion to recover from Stop state
Delay from IRQA assertion to fetch of first instruction (when
exiting Stop)
Duration of level sensitive IRQA assertion to ensure interrupt
service (when exiting Stop)
