FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Figure 22. CAN Bus Signal During Can Sleep State and Wake-up Sequence
Figure 23 illustrates how the wake-up signal is generated. First the CAN signal is detected by a low consumption receiver (WU
receiver). Then the signal passes through a pulse width filter, which discards the undesired pulses. The pulse must have a width
bigger than 0.5
s and smaller than 500 s to be accepted. When a pulse is discarded, the pulse counter is reset and no wake-
up signal is generated. When a pulse is accepted, the pulse counter is incremented and, after three pulses, the internal wake-up
signal is asserted.
Each one of the pulses must be spaced by no more than 500
s. If not, the counter will be reset and no wake-up signal will be
generated. This is accomplished by the wake-up timeout generator. The wake-up cycle is completed (and the wake-up flag reset)
when the CAN interface is brought to CAN Normal mode.

CAN WAKE-UP REPORT
The CAN wake-up reporting depend upon the low power mode the SBC is in.
If the SBC is placed into Sleep mode (VDD and V2 off), the CAN wake-up or any wake-up results in the VDD regulator turning
on, leading to turning on the MCU supply and releasing reset. If the 33742 is in Stop mode (V2 off and VDD active), the CAN
wake-up or any wake-up is signalled by a pulse on the INT output. In addition the CANWU bit is set in the CAN register.
If the SBC is in Normal or Standby mode and the CAN interface is in Sleep mode with wake-up enabled, the CAN wake-up is
reported by the CANWU bit in the CAN register.
In the event the SBC is in Normal mode and CAN Sleep mode with wake-up enabled, it is recommended that the user check
for the CANWU bit prior to placing the 33742 in Sleep or Stop mode in case bus traffic has occurred while the CAN interface was
in Sleep mode.
