• Bit 7—Bit Sample Point (BSP): Sets the point at which data is sampled.
Bit 7: BCR15

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 1 time
quantum before and after)
• 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.

TSEG2 (PHSEG2) = 6 time quanta
TSEG2 (PHSEG2) = 7 time quanta
TSEG2 (PHSEG2) = 8 time quanta
(Initial value)
• 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 from 4 to 16 can be set.
