6. Functional description

6.1 Power modes

The TJA1083 features three power modes: Normal, Standby and Power-off. Normal and

Standby modes can be selected via the STBN input (HIGH for Normal mode) once the

transceiver has been powered up. See Table 3 for a detailed description of pin signaling in

the three power modes.
