12.1.1
The Interrupt for Vcc2 and Vcc3 are generated when the SPI command for switching on the voltage regulator is
executed. The interrupt bit is set to “1“ and can be cleared with a Read Only command after the under voltage
threshold is reached. If the Read Only is done before the reset threshold is reached, the interrupt bit can not be
cleared as the undervoltage condition is still present. In this case a second interrupt can be issued for releasing
the undervoltage condition.
In case of a short to GND on Vcc2 or Vcc3 the interrupt for switching on the voltage regulator is issued, but the
µC can not clear the interrupt bit as the voltage regulator does not reach the undervoltage threshold.
12.1.2
The examples show single interrupt events. SPI read is done with “Read Only”. The shown interrupts are not
masked. Watchdog trigger is not shown in the examples.
The interrupt UV_Vcc2 that is generated by switching on
rising event only.
