TLE8262E

High Speed CAN Transceiver

8.2.3

CAN OFF Mode

CAN OFF Mode, which can be accessed in the SBC Stop, Sleep, Restart and Normal modes, and automatically

accessed in SBC Init and Factory Flash modes, is used to completely stop CAN activities. In CAN OFF Mode, a

wake up event on the bus will be ignored.

8.2.4

CAN Receive Only Mode

In CAN Receive Only Mode (RxD only), the driver stage is de-activated but reception is still operational. This mode

is accessible by an SPI command.

8.2.5

CAN Cell in Disabled State

During disable state, when

s < VUV_OFF, the CAN cell does not have enough supply voltage. In this state, the

CANH and CANL pins are set to high impedance, to guarantee passive behavior. The maximum current that can

flow in the CANH and CANL pins in this mode are specified by

CANH,lk and ICANL,lk.

8.3

CAN Cell Mode with SBC Mode

Table 7 shows all the CAN modes accessible to the current SBC Mode. Automatic transition from one CAN mode

to an other is only allowed in the same column.

8.3.1

SBC Normal Transition to Sleep or Stop Mode

During the transition from SBC Normal to Sleep or Stop Modes, the receiver module is deactivated and replaced

by the low power mode receiver for wake-up capability. The next message can be only a wake-up call. It is possible

to set the SBC directly from SBC Normal Mode (with CAN Normal Mode) to SBC Sleep or Stop Mode, but this is

not recommended, because a wake pattern on the CAN network that could occurs during SPI communication

could get lost. It is preferable, in SBC Normal Mode to first send the CAN transceiver into CAN Wake Capable

Mode, and then set the entire device to SBC Sleep or Stop Mode. In the unlikely case that the device would see

a wake up call during the transmission order “SBC go to sleep”, the device will store this event and bypass the

“SBC go to sleep” command to go back into SBC Restart Mode.

Do not change the Transciever setting with the same SPI command that is used to sent the device to Sleep Mode.

8.3.2

Transition from SBC Sleep to other Modes

In SBC Sleep Mode, a wake-up on the CAN cell will set the SBC to Restart Mode automatically if the CAN Wake

Capable Mode of the SBC is selected via SPI. Figure 11 shows the typical timing.
