Standby Mode

A high level on the STBY pin (PB25) selects Standby mode. In this mode, the transceiver is not able to transmit or receive data via the bus lines. The transmitter and the high-speed comparator are switched off to reduce the power current consumption.

For more details on the module, refer to the product web page.

The figure below illustrates the implementation of the dual CAN interface.
