Functional Description and Application Information
4.6.1.2
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.
