ened when resynchronizing. Values between "1" (<SJW[1:0]> 00) and "4" (<SJW[1:0]> 11) are adjustable. The
bus line is sampled and synchronization is performed at each falling edge of the bus signal within a bit grid. For
<SJW[1:0]>, set a value equal to or smaller than <TSEG2[2:0]>.
from the majority decision of three sampling values. Sampling is taken at the sample point and the previous last
two CAN system clock points. When <BRP[9:0]> is smaller than 4, the sampling performed is always once regard-
less of the value set in the <SAM> bit.
ta transmission rate has to be programmed with a length of 12T
be programmed always are smaller by one than the calculated values:
Thus, SAM="0" should be set.
<SJW[1:0]> indicates how much the time quantum (T
Setting the <SAM> bit enables the multiple sampling of the bus line. The level is determined by the result
Table 16-2 shows the restrictions when the baud rate is set.
Example : For 500 Kbit/s
A bit has a length of 2μs. If fOSC = 12 MHz,. the baud rate prescaler is set to "1". That means a bit for this da-
<BRP[9:0]> = 0y00_0000_0001
<TSEG1[3:0]> = 0y0110 (7 TQ)
<TSEG2[2:0]> = 0y011 (4 TQ)
In this case, the sample point is 8/12 66%.
Other combinations for TSEG1 / TSEG2 are possible; with TSEG2 3 the full range for SJW.
SJW should always be set to the highest value possible. SJW is not allowed to be greater than TSEG2.
The three-time sampling of the bus cannot be set because of the condition that <BRP[9:0]> is smaller than 4.

TSEG1 ≥ TSEG2 : The length of TSEG1 should be equal to or greater than the length of TSEG2.
SJW ≤ TSEG2 : For the synchronization jump width, set a value equal to or smaller than TSEG2.
