Figure 27. CAN Wake-Up
T1(third valid CAN dominant pulse to V

turn on): typ
80 μs.
T2 and T3 identical to page

above
The total time is 6.58 ms in this example.
LX with Cyclic Sense
The case below is a description of the wake-up by LX input
associated with the cyclic sense function.
Figure 28.
T1: Is dependent on the selected cyclic sense timing in
the TIM2 register (5 ms to 400 ms). LX is sampled
10 μs before the end of cyclic sense on time. If the LX
correct wake-up level happens just after the sample
point, the wake-up will be detected at the next HS1
activation and a complete period is lost.
T2: It is the same time as LX to VDD1 turn on: typ
100 μs
T3 & T4: same as page
39
The total time is 11.5 ms (for a cyclic sense total time of
5 ms) in this example.
WAKE-UP TIMING: STOP MODE
The following paragraphs describe the wake-up events
from stop mode, and the sequence of the signals at the SBC
level. The wake-up time described is the time from the wake-
up event to the SBC INT pin. The wake-up time is the sum of
several timings: wake-up signal detection, the INT pulse, and
a minimum delay between INT and SBC ready to operate. At
the end of the wake-up time, the SBC is ready to operate,
however the MCU might have already been in a restart
operation.
LX Wake-Up
Below is the case where the SBC is in stop mode and is
awakened by an LX positive edge
T1(L0 high level to INT pulse): typ 100 μs.
The total time is 133 μs in this case.
