PLL is not active during Stop (PCTL Bit 17 = 0) and Stop delay is
enabled (Operating Mode Register Bit 6 = 0)
PLL is not active during Stop (PCTL Bit 17 = 0) and Stop delay is not
enabled (Operating Mode Register Bit 6 = 1)
PLL is active during Stop (PCTL Bit 17 = 1) (Implies No Stop Delay)
PLL is not active during Stop (PCTL Bit 17 = 0) and Stop delay is
enabled (Operating Mode Register Bit 6 = 0)
PLL is not active during Stop (PCTL Bit 17 = 0) and Stop delay is not
enabled (Operating Mode Register Bit 6 = 1)
PLL is active during Stop (PCTL Bit 17 = 1) (implies no Stop delay)
