15.5.2
The bit rate and bit timing are set by the bit configuration register (BCR). The CAN controllers
connected to the CAN bus should be set so that all of them have the same baud rate and same bit
width. One bit time consists of total settable Time Quantum (TQ).
The SYNC_SEG is a segment for establishing the synchronization of nodes on the CAN bus.
Normal bit edge changes in this segment. The PRSEG is a segment for adjusting the physical
delay between networks. The PHSEG1 is a buffer segment for adjusting positive phase drift. This
segment is extended when re-synchronization is established. The PHSEG2 is a buffer segment for
adjusting negative phase drift. This segment is shortened when re-synchronization is established.
The range of settable values in BCR (TSG1, TSG2, BRP, and SJW) is shown in table 15.2.
Table 15.2 Settable Values in BCR
Notes: 1. The time quanta values for the TSEG1 and TSEG2 are as follows: TSG value
