21.15 Baud Rate Settings
21.15.1 Bit rate setting conditions
as follows.
1144
Make sure that the settings are within the range of limit values for ensuring correct operation of the CAN controller,
Table 21-22 shows the combinations of bit rates that satisfy the above conditions.
Remark TQ = 1/f
(a) 5TQ ≤ SPT (sampling point) ≤ 17 TQ
(b) 8 TQ ≤ DBT (data bit time) ≤ 25 TQ
(c) 1 TQ ≤ SJW (synchronization jump width) ≤ 4TQ
(d) 4TQ ≤ TSEG1 ≤ 16TQ [3 ≤ Setting value of TSEG1[3:0] ≤ 15]
(e) 1TQ ≤ TSEG2 ≤ 8TQ [0 ≤ Setting value of TSEG2[2:0] ≤ 7]
SPT = TSEG1 + 1TQ
DBT = TSEG1 + TSEG2 + 1TQ = TSEG2 + SPT
