Notes
1. When oscillation mode selection (OSMS) register is set at 00H.
2. When OSMS is set at 01H.
3. In combination with bits 0 (SCS0) and 1 (SCS1) of sampling clock select register (SCS), selection
of fsam is possible between fXX/2^N, fXX/32, fXX/64 and fXX/128 (when N = 0 to 4).
Remarks 1. fXX: System clock frequency (fX or fX/2)
2. fX: System clock oscillation frequency
