VMM - Voltage Monitor Interrupt Mask
the Voltage Monitor block. The only maskable interrupt in the
Voltage Monitor Block is the V
Interrupt Source Register - ISR
the last interrupt or wake-up respectively. A read of the
register acknowledges the interrupt and leads IRQ pin to
high, in case there are no other pending interrupts. If there
are pending interrupts, IRQ will be driven high for 10µs and
then be driven low again.
