FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
CAN SIGNALS IN TXRX AND SLEEP MODES
When the CAN interface is set back into TXRX mode by an SPI command, CAN H and CANL are set in recessive level. This
is illustrated in Figure 21.
Figure 21. CAN Signals in TXRX and Sleep Modes
CAN IN SLEEP MODE WITH WAKE-UP ENABLE
When the CAN interface is in Sleep mode with wake-up enable, the CAN bus traffic is detected. The CAN bus wake-up is a
pattern wake-up.
PATTERN WAKE-UP
In order to wake up the CAN interface, the following criteria must be fulfilled:
The CAN interface wake-up receiver must receive a series of three consecutive valid dominant pulses, each of which must be
longer than 500 ns and shorter than 500
s.
The distance between 2 pulses must be lower than 500
s.
The three pulses must occur within a time frame of 1.0 ms.
The pattern wake-up of the 33742 CAN interface allow wake-up by any CAN message content.
Figure 22 below illustrates the CAN signals during a CAN bus Sleep state and wake-up sequence.
