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