The SAM bit determines the number of sampling points to be taken per bit.
When the SAM bit is set to 0, only one sample is taken per bit at the end of the Phase Buffer Segment 1 (PBS1)
to determine the value of the bit.
When the SAM bit is set to 1, three samples per bit are taken; one time quantum and two time quanta before the
end of PBS1, and at the end of PBS1. The value detected twice or more becomes the value of the sampled bit.
Bits PTS2 to PTS0 determine the number of Tq for PTS.
Bits PBS12 to PBS10 determine the number of Tq for PBS1. Set bits PBS12 to PBS10 to other than 000b.
Bits PBS22 to PBS20 determine the number of Tq for PBS2. Set bits PBS22 to PBS20 to other than 000b.
Bits SJW1 and SJW0 determine the number of Tq for SJW.
