System Wake-Up
bit for this event is set, the interrupt will wake up the
microcontroller as well as the main voltage regulator (MREG)
(Figure

System wake-up can be initiated by any of four events:
• A falling edge on the LIN terminal.
• A wake-up signal from the AWD.
• A logic [1] at Hall-effect sensor input terminal during cyclic
• An LVR condition.
If one of these wake-up events occurs and the interrupt mask
check via AWD.

Interrupt Flag Register (IFR)
HPF—Hall-Effect Sensor Input Terminal Flag Bit

the HPF bit. Writing a logic [0] to HPF has no effect.
set and a current above the threshold is detected on any
enabled Hall-effect sensor input terminal. Clear HPF by writing
a logic [1] to HPF. Reset clears the HPF bit. Writing a logic [0]
to HPF has no effect.
LINF—LIN Flag Bit
line. Clear LINF by writing a logic [1] to LINF. Reset clears the
LINF bit. Writing a logic [0] to LINF has no effect.
HTF—High-Temperature Flag Bit
Clear HTF by writing a logic [1] to HTF. If a high-temperature
condition is still present while writing a logic [1] to HTF, the
writing has no effect. Therefore, a high-temperature interrupt
cannot be lost due to inadvertent clearing of HTF. Reset clears
the HTF bit. Writing a logic [0] to HTF has no effect.

This read/write flag is set depending on RUN/STOP mode.
RUN Mode An interrupt will be generated when a state
• 1 = State change on the hallflags detected.
• 0 = No state change on the hallflags detected.
STOP Mode An interrupt will be generated when AWDCC is
• 1 = One or more of the selected Hall-effect sensor input
• 0 = None of the selected Hall-effect sensor input terminals
This read/write flag is set on the falling edge at the LIN data
• 1 = Falling edge on LIN data line has occurred.
• 0 = Falling edge on LIN data line has not occurred since
This read/write flag is set on
• 1 = High-temperature condition has occurred.
• 0 = High-temperature condition has not occurred.
