This bit determines the number of serial bus samples to be taken per
bit time. If set, three samples per bit are taken, the regular one
(sample point) and two preceding samples, using a majority rule. For
higher bit rates, SAMP should be cleared, which means that only one
sample will be taken per bit.
Time segments within the bit time fix the number of clock cycles per
bit time and the location of the sample point.
Time segment 1 (TSEG1) and time segment 2 (TSEG2) are
programmable as shown in
For More Information On This Product,
1 = Three samples per bit
0 = One sample per bit
