INTERRUPTS
The 908E626 has six different interrupt sources as
described in the following paragraphs. The interrupts can be
disabled or enabled via the SPI. After reset all interrupts are
automatically disabled.
LOW VOLTAGE INTERRUPT
The Low Voltage Interrupt (LVI) is related to the external
supply voltage, VSUP. If this voltage falls below the LVI
threshold, it will set the LVI flag. If the low voltage interrupt is
enabled, an interrupt will be initiated.
With LVI the H-bridges (high side MOSFET only) are
switched off. All other modules are not influenced by this
interrupt.
During STOP mode the LVI circuitry is disabled.
HIGH VOLTAGE INTERRUPT
The High voltage Interrupt (HVI) is related to the external
supply voltage, VSUP. If this voltage rises above the HVI
threshold, it will set the HVI flag. If the High voltage Interrupt
is enabled, an interrupt will be initiated.
With HVI the H-bridges (high side MOSFET only) are
switched off. All other modules are not influenced by this
interrupt.
During STOP mode the HVI circuitry is disabled.
HIGH TEMPERATURE INTERRUPT
The High Temperature Interrupt (HTI) is generated by the
on-chip temperature sensors. If the chip temperature is
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 HTI circuitry is disabled.
AUTONOMOUS WATCHDOG INTERRUPT (AWD)
LIN INTERRUPT
If the LINIE bit is set, a falling edge on the LIN pin will
generate an interrupt. During STOP mode this interrupt will
initiate a system wake-up.
OVER-CURRENT INTERRUPT
If an over-current condition on a half-bridge or the HVDD
output is detected and the OCIE bit is set and an interrupt
generated.
SYSTEM WAKE-UP
System wake-up can be initiated by any of four events:
A falling edge on the LIN pin
A wake-up signal from the 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)
