5.4.4
On S12G devices, the CPU and the BDM are not able to access the memory in parallel. An arbitration
occurs whenever both modules attempt a memory access at the same time. CPU accesses are handled with
higher priority than BDM accesses unless the BDM module has been stalled for more then 128 bus cycles.
In this case the pending BDM access will be processed immediately.
5.4.5
The S12GMMC does not generate any interrupts.
