The SAM bit determines the number of sample 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 sample result value which is detected
more than twice becomes the value of the bit sampled.
The PTS2 to PTS0 bits determine PTS width.
The PBS12 to PBS10 bits determine PBS1 width. Set the PBS12 to 10 bits to "001
The PBS22 to PBS20 bits determine PBS2 width. Set the PBS22 to PBS20 bits to "001
The SJW1 and SJW0 bits determine SJW width. Set the SJW1 and SJW0 bits to values less than or
equal to the PBS22 to PBS20 bits and the PBS12 to PBS10 bits.
