disabled or enabled via the SPI. After reset all interrupts are
automatically disabled.

enabled, an interrupt will be initiated.
high-side driver are switched off. All other modules are not
influenced by this interrupt.
HIGH-VOLTAGE INTERRUPT

is enabled, an interrupt will be initiated.
high-side driver are switched off. All other modules are not
influenced by this interrupt.
HIGH-TEMPERATURE INTERRUPT

above the HTI threshold, the HTI flag will be set. If the High-
Temperature Interrupt is enabled, an interrupt will be
initiated.

During STOP mode the LVI circuitry is disabled.
The High-Voltage Interrupt (HVI) is related to the external

initiate a system wake-up.
HALL-EFFECT SENSOR INPUT PIN INTERRUPT
pins H1:H3 can generate an interrupt if a current above the
threshold is detected. During STOP mode this interrupt,
combined with the cyclic wake-up feature of the AWD, can
wake up the system. Refer to pin
