Section 19 Controller Area Network (RCAN-ET)
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.
Bits 7 and 6 : Reserved. The written value should always be '0' and the returned value is '0'.
Bits 5 and 4 - ReSynchronisation Jump Width (SJW[1:0] = BCR0[5:4]): These bits set the
synchronisation jump width.
Bits 3 to 1 : Reserved. The written value should always be '0' and the returned value is '0'.
Bit 0 — Bit Sample Point (BSP = BCR1[0]): Sets the point at which data is sampled.
