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
