Freescale Semiconductor

4.6.1.2

Interrupt Vector Emulation by Priority

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.
