FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
VMM - Voltage Monitor Interrupt Mask
This write-only bit enables/disables interrupts generated in
the Voltage Monitor block. The only maskable interrupt in the
Voltage Monitor Block is the V SUP over-voltage interrupt.
This register is also returned when writing to the Interrupt
Mask Register (IMR).

Interrupt Source Register - ISR
This register allows the MCU to determine the source of 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.
Table 31. Interrupt Sources
ISRx - Interrupt Source Register
These read-only bits indicate the interrupt source following
Table 31 . If no interrupt is pending then all bits are 0.
In case more than one interrupt is pending, the interrupt
sources are handled sequentially multiplex.
