FAIL-SAFE OPERATION
BEHAVIOR AT POWER UP AND POWER DOWN
.
Figure 30. Safe Operation Flow Chart
Conditions to Set SAFE Pin Active Low
Watchdog refresh issue: SAFE activated at 1st reset pulse
or at the second consecutive reset pulse (selected by bit 4,
INIT watchdog register).
VDD low: VDD < RST-TH. SAFE pin is set low at the same
time as the RST pin is set low.
The RST pin is monitored to verify that reset is not
clamped to a low level preventing the MCU to operate. If this
is the case, the Safe mode is entered.

Failure events
1) bit 4 of INIT Watchdog register
2) Wake-up event: CAN, LIN or I/O-1 high level (if I/O-1 Wake-up previously enabled)
3) SPI commands: 0xDD00 or 0xDD80 to release SAFE pin
4) Recovery: reset low condition released, VDD low condition released, correct SPI watchdog refresh
5) detection of 8 consecutive watchdog failures: no correct SPI watchdog refresh command occurred for duration of 8 x 256 ms.
6) Dynamic behavior: 1.0 ms reset pulse every 256 ms, due to no watchdog refresh SPI command, and device state transition
