S is not used to indicate actual clock always.
'S' is only used to indicate the "deep sleep state" of the clock. If the
clock is at deep sleep frequency ex: 95MHz, it's indicated by special
level S.
S:95Mhz*
0:500Mhz
1:1900Mhz
If the clock is active and operating as normal ex:1120MHz, the level is
not indicated by S. Sample values at that state will be
0:500Mhz
1:1120Mhz*
2:1900Mhz
Thanks,
