18.15 Baud Rate Settings
18.15.1 Baud rate setting conditions
Make sure that the settings are within the range of limit values for ensuring correct operation of the CAN
Controller, as follows.
•

≤
SPT (sampling point)
≤
17 TQ
SPT = TSEG1 + 1
•

≤
DBT (data bit time)
≤
25 TQ
DBT = TSEG1 + TSEG2 + 1TQ = TSEG2 + SPT
•
