25 Delay from IRQA assertion to fetch of first instruction (when
exiting Stop)3, 8
• PLL is not active during Stop (PCTL Bit 17 = 0) and Stop
delay is enabled (OMR Bit 6 = 0)
• PLL is not active during Stop (PCTL Bit 17 = 0) and Stop
delay is not enabled (OMR Bit 6 = 1)
• PLL is active during Stop (PCTL Bit 17 = 1) (Implies No
