MUARD – DMH Unified Access Register Data
DMH Unified Access Registers
The DMH provides the MUARS and MUARD registers, which allow access to information in the
high-speed core. These registers are read and written through the MSIO serial interface (see
Section 4.11, “Serial
To read or write information to the high-speed core through this interface, first write the MUARS
register SELECT field with the entry to be accessed. Then, to write data to the entry selected, write
the data to the MUARD register. Or to read data from the entry selected, read the MUARD
register. Some entries are read-only as indicated in
