R/W Time Segment 2
R/W ^{These bits are used to set the segment for}
correcting a 1-bit time error. A value from 2 to 8
R/W _{time quanta can be set as shown below.}
000: Setting prohibited
001: PHSEG2 = 2 time quanta (Conditionally
prohibited. See table 22.2.)
010: PHSEG2 = 3 time quanta
011: PHSEG2 = 4 time quanta
100: PHSEG2 = 5 time quanta
101: PHSEG2 = 6 time quanta
110: PHSEG2 = 7 time quanta
111: PHSEG2 = 8 time quanta

R/W ReSynchronization Jump Width
R/W ^{These bits set the synchronization jump width.}
00: Synchronization jump width = 1 time quantum
01: Synchronization jump width = 2 time quanta
10: Synchronization jump width = 3 time quanta
11: Synchronization jump width = 4 time quanta

R/W Edge Select
Selects at which edge is to be used for re-
synchronization. In order to comply to the
standard CAN, this bit should be cleared to 0.
0: Re-synchronization is performed at falling edge
of Rx.
1: Re-synchronization is performed at both rising
and falling edge of Rx.
R/W Bit Sample Point
Sets the point at which data is sampled. Three-
time sampling is only available when the BRP 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)
