Clock Module
9-20
SCM
Note:
PLL = PLL enabled during STOP mode. PLL = On when STPMD[1:0] = 00 or 01
OSC = Oscillator enabled during STOP mode. Oscillator is on when STPMD[1:0] = 00, 01, or 10
MODES
NRM = normal PLL crystal clock reference or normal PLL external reference or PLL 1:1 mode. During PLL 1:1 or
EXT=external clock mode
REF=PLL reference mode due to losing PLL clock or lock from NRM mode
SCM=PLL self-clocked mode due to losing reference clock from NRM mode
RESET= immediate reset
LOCKS
‘LK= expecting previous value of LOCKS before entering stop
0–>‘LK= current value is 0 until lock is regained which then will be the previous value before entering stop
0–> = current value is 0 until lock is regained but lock is never expected to regain
LOCS
‘LC=expecting previous value of LOCS before entering stop
1–>‘LC= current value is 1 until clock is regained which then will be the previous value before entering stop
1–> =current value is 1 until clock is regained but CLK is never expected to regain
MODE
normal external reference mode, the oscillator is never enabled. Therefore, during these modes, refer to the OSC =
On case regardless of STPMD values.
