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
V
bat
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
),
V
CC
is the status of the voltage regulator.

V
bat
stand-by mode and sleep mode
In the V
bat
stand-by mode and sleep mode the RTL output voltage is switched to V
S
.
Both modes are low power modes. In the sleep mode the whole application is switched
