The following subsections describe the configuration and status registers
in detail.
CPU Configuration Register
The CPU Configuration register is an 8-bit register located at ISA I/O
address x0800. This register is defined for the MVME2300 series to
provide some backward compatibility with older MVME1600 products.
The Base Module Status register should be used to identify the base
module type and the System Configuration register should be used to
obtain information about the overall system.
CPUTYPE
CPU Type. This field will always read as $E for the
MVME2300 series. (The whole register will read $EF.)
The System Configuration register should be used for
additional information.
