Memory Map
This table is constructed to show the correct values when read and written via the system bus MPI interface. When
using this table while interfacing with the system bus user logic master interface, the data values will need to be
byte flipped. This is due to the opposite orientation of the MPI and master interface bus ordering. More information
on this can be found in the MPI/System Bus Application Note (AP01-032NCIP).
Table 11. Memory Map (This table resides at memory offset 0X30000 in the ORT8850.)
