Delay from IRQA, IRQB, IRQC, IRQD, NMI assertion to
external memory access address out valid
Delay from IRQA, IRQB, IRQC, IRQD, NMI assertion to
general-purpose transfer output valid caused by first interrupt
instruction execution
Delay from address output valid caused by first interrupt
instruction execute to interrupt request deassertion for level
sensitive fast interrupts
Delay from RD assertion to interrupt request deassertion for
level sensitive fast interrupts

exiting Stop)
Duration of level sensitive IRQA assertion to ensure interrupt
service (when exiting Stop)
• Caused by first interrupt instruction fetch
• Caused by first interrupt instruction execution
• DRAM for all WS
• SRAM WS = 1
• SRAM WS = 2, 3

• PLL is not active during Stop (PCTL Bit 17 = 0) and Stop
• PLL is not active during Stop (PCTL Bit 17 = 0) and Stop
• PLL is active during Stop (PCTL Bit 17 = 1) (Implies No
• PLL is not active during Stop (PCTL Bit 17 = 0) and Stop
• PLL is not active during Stop (PCTL Bit 17 = 0) and Stop
• PLL is active during Stop (PCTL Bit 17 = 1) (implies no
