Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Size of Local Address Space 1 (9 bits)
Specify the size of local address space 1
(SuperHyway bus address space of this LSI) in units
of Mbyte. The value set in these bits must be the size
minus 1 Mbytes. Setting all the bits to 0 ensures 1-
Mbyte space.
