HS CAN Transceiver

High Speed CAN Transceiver

Changing the mode of operation

6.2

Mode change by the RM pin

When the TLE9250X is supplied with the digital voltage VIO the internal logic works and mode change by the

mode selection pin RM is possible.

By default the RM input pin is logical “low” due to the internal pull-down current source to GND. Changing the

RM input pin to logical “high” in Normal-operating mode triggers a mode change to Receive-only mode (see

Figure 7). To enter Normal-operating mode or Receive-only mode the transmitter supply VCC needs to be

available.
