# OMR notes:
# ----------------------------------------------
# the DSP56836E OMR is same as DSP56807 OMR

# the operating mode control bits (MA and MB) 
# in the Operating Mode Register (OMR)
# control the program memory map.

# at reset, these bits are set to the value 
# present on the external EXTBOOT pin (JG3 for 56836E)

# OMR EX sets the data memory to internal or internal.


# OMR bits:         zero                     one

#   EX 3     internal RAM and flash  |    external*
