• The access column indicates if the corresponding register allows both read/write
functionality (R/W), read-only functionality (R), or write-only functionality (W). An
attempted read access to a write-only register returns zeros. An attempted write access
to a read-only register is ignored and no write occurs.
8.3.2 SIM Registers
8.3.2.1 MODULE BASE ADDRESS REGISTER (MBAR). The MBAR determines the base
address location of all internal module resources such as registers as well as the definition
of the types of accesses that are allowed for these resources.
The MBAR is a 32-bit write-only supervisor control register that physically resides in the SIM.
It is accessed in the CPU address space via the MOVEC instruction with an Rc encoding of
$C0F. The MBAR can be read and written to when in Background Debug mode (BDM). At
system reset, the V bit is cleared and the remainder of the MBAR bits are uninitialized. To
access the internal modules, MBAR should be written with the appropriate base address
after system reset.
