Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Internal Memory Space Base Address
These bits set the base address of the memory space
used for access to the internal memory by the external
CPU.
The address of the memory space to be accessed is
comprised as follows:
31st and 30th bits: Fixed at B'01
29 to 26th bits: EXCMSET[3:0]
25 to 0th bits: Access address from the external CPU
The address range of the memory space accessible to
the external CPU is from H'4000 0000 to H'7FFF FFFF.
