Bit 11: Reserved. The written value should always be '0' and the returned value is '0'.
Bits 10 to 8 — Time Segment 2 (TSG2[2:0] = BCR1[10:8]): These bits are used to set the
segment TSEG2 ( = PHSEG2) to compensate for edges on the CAN Bus with a negative phase
error. A value from 2 to 8 time quanta can be set as shown below.
