3. Connect to enabled port to control CAN transceiver.
1. The pin which controls the operation mode of CAN transceiver.
2. In case of Topr = 25°C
3. Connect to enabled port to control CAN transceiver.
When not performing CAN communication, the operation mode of CAN transceiver should be set to “standby
mode” or “sleep mode”.
When performing CAN communication, the power consumption in CAN transceiver in not performing CAN
communication can be substantially reduced by controlling the operation mode pins of CAN transceiver.
Table 22.3 and Table 22.4 show Recommended Pin Connections.
