Preliminary
6.4 Operating Mode Register
Figure 6-1 OMR
The reset state for the MB bit will depend on the Flash secured state. See Section 4.2 and Part 7 for
detailed information on how the Operating Mode Register (OMR) MA and MB bits operate in this device.
The EX bit is not functional in this device since there is no external memory interface. For all other bits,
see the 56F8300 Peripheral User Manual.
Note: The OMR is not a Memory Map register; it is directly accessible in code through the acronym OMR.
