Description
Bit sampling at one point (end of time segment 1 (TSEG1)) (Initial value)
Bit sampling at three points (end of time segment 1 (TSEG1) and preceding
and following time quanta)
Bits 6 to 4—Time Segment 2 (TSEG2): These bits are used to set the segment for correcting 1-
bit time error. A value from 2 to 8 can be set.
