4.7.1.2
To allow a vector based interrupt handling by the MCU, the number of the highest prioritized interrupt pending is returned in the
Interrupt Vector Register. To allow an offset based vector table, the result is pre-shifted (multiple of 2). Reading this register will
not acknowledge an interrupt. An additional D2D access is necessary to serve the specific module.

4.7.2.1
The Voltage Status Interrupt - VSI combines the five interrupt sources of the Voltage Status Register. It is only available in the
Interrupt Source Register (ISR). Acknowledge the interrupt by reading the Voltage Status Register - VSR. To issue a new
