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.

Bits 3 to 0—Time Segment 1 (TSEG1): These bits are used to set the segment for absorbing
output buffer, CAN bus, and input buffer delay. A value of 1 or 4 to 16 can be set.
