MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
System Wake-Up
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
check via AWD.
An LVR condition.
If one of these wake-up events occurs and the interrupt mask
bit for this event is set, the interrupt will wake up the
microcontroller as well as the main voltage regulator (MREG)
(
Figure 6
).

Hall-Effect Sensor Input Terminal Flag Bit
This read/write flag is set depending on RUN/STOP mode.
RUN Mode
An interrupt will be generated when a state
change on any enabled Hall-effect sensor input terminal is
detected. Clear HPF by writing a logic [1] to HPF. Reset clears
the HPF bit. Writing a logic [0] to HPF has no effect.
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
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.
1 = One or more of the selected Hall-effect sensor input
terminals had been pulled HIGH.
0 = None of the selected Hall-effect sensor input terminals
has been pulled HIGH.
LINF
—
LIN Flag Bit
This read/write flag is set on the falling edge at the LIN data
line. Clear LINF by writing a logic [1] to LINF. Reset clears the
LINF bit. Writing a logic [0] to LINF has no effect.
1 = Falling edge on LIN data line has occurred.
0 = Falling edge on LIN data line has not occurred since
last clear.
HTF
—
High-Temperature Flag Bit
This read/write flag is set on
a
high-temperature condition.
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.
1 = High-temperature condition has occurred.
0 = High-temperature condition has not occurred.
