VBAT_standby mode
The transition from active mode to VBAT_standby mode is initiated by an SPI command (STBY_SEL bit and
GO_STBY bit in CR2).
In VBAT_standby mode, the voltage regulators V1 and V2, the power outputs as well as LIN and CAN
transmitters are switched off.
An NReset pulse is generated and last asserted low upon wake-up from VBAT_standby mode and until 2ms after
LDO1 is fully operative.

Wake-up from standby modes
A wake-up from standby mode switches the device to active mode. This can be initiated by one or more of the
following events:
Table 7. Wake-up source
Wake-up source
Description
LIN bus activity
It can be disabled by SPI
CAN bus activity
It can be disabled by SPI
Level change of WU
It can be configured or disabled by SPI
IV1 > Icmp
The device remains in V1_standby mode but watchdog is enabled (if ICMP = 0).
No interrupt is generated.
Timer interrupt /
Wake-up of μC by TIMER
Programmable by SPI:
- V1_standby mode:
device wakes up and interrupt signal is generated at NINT when
programmable time-out has elapsed
- VBAT_standby mode: device wakes up after programmable timer expiration. V1 regulator
is turned on and NReset signal is generated when programmable time-out has elapsed
SPI access
Always active (except in VBAT_standby mode)
Wake-up event: CSN falling edge
To prevent the system from a deadlock condition (no wake-up from standby possible) a configuration where all
wake-up is disabled, is not allowed.
Accordingly, if the following condition is set by SPI:
•
CAN_WU_EN = 0
•
LIN_WU_EN = 0
•
WU1_EN = 0
•
WU2_EN = 0
The effect is to put all these register bits in their default condition:
•
CAN_WU_EN = 1
