LIN Buses and
RS-232 Lines
Table 3-2. Pinout
The CAN bus resistive load is 60 Ohm. It is made up of two 120 Ohm resistors in paral-
lel. The recommended CAN bus load is 60 Ohm. Depending on the external input bus
resistor, users can disconnect resistors to achieve the correct bus load.
For more details, refer to Figure 4-5.
