Operation Modes

The TLE 6263 offers four different operation modes that are controlled via the SPI

interface (NSTB= SPI Input Bit3, ENT=SPI Input Bit2): the normal operation mode, the

receive-only mode, the Vbat stand-by mode and the sleep operation mode. Please see

the state diagram (figure 3).

Normal and Receive only Mode

In the normal operation mode both is possible, receiving and transmitting of messages,

in the receive-only mode (RxD-only mode) the output stages are disabled which doesn’t

allow the CAN controller to send a message to the bus. In the state diagram (figure 3),

VCC is the status of the voltage regulator.

Vbat stand-by mode and sleep mode

In the Vbat stand-by mode and sleep mode the RTL output voltage is switched to VS.

Both modes are low power modes. In the sleep mode the whole application is switched
