R/W Re-Synchronization Jump Width (SJW[1:0] =
R/W
BCR0[5:4])
Set the synchronization jump width.
00: 1 time quantum
01: 2 time quanta
10: 3 time quanta
11: 4 time quanta

The write value should be 0. The read value is not
guaranteed.

EG
0
R/W Edge Select (EG = BCR1[1])
Selects at which edge is to be used for re-
synchronization. In order to comply with the
standard CAN, 0 should be set.
0: Re-synchronization is performed at falling edge
of Rx
1: Re-synchronization is performed at both rising
and falling edges of Rx
0
BSP
0
R/W Bit Sample Point (BSP = BCR1[0])
Sets the point at which data is sampled.
Important: Sampling at three points is only
available when the BRP[7:0] is programmed to be
less than 4.
0: Bit sampling at one point (end of time segment
1)
1: Bit sampling at three points (end of time
segment 1, and 1 time quantum before and
after)
