• 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)

(Initial value)

Bit sampling at three points (end of time segment 1, 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.

Bit 6:

BCR14

Bit 5:

BCR13

Bit 4:

BCR12

Description

Setting prohibited

(Initial value)

TSEG2 (PHSEG2) = 2 time quanta

TSEG2 (PHSEG2) = 3 time quanta

TSEG2 (PHSEG2) = 4 time quanta

TSEG2 (PHSEG2) = 5 time quanta

TSEG2 (PHSEG2) = 6 time quanta

TSEG2 (PHSEG2) = 7 time quanta

TSEG2 (PHSEG2) = 8 time quanta

• 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 1 to 16 can be set.

Bit 3:

BCR11

Bit 2:

BCR10

Bit 1:

BCR9

Bit 0:

BCR8
