I/O Address Map

20.4
The I/O-port addresses of the processor module MOPS/386A are functionally identical to a
standard PC/AT. All addresses not mentioned in this table should be available. We
recommend that you do not use I/O addresses below 0110hex with additional hardware for
compatibility reasons, even if they are available on the MOPS/386A.

Note: The Super I/O Controller is connected to ISA address lines A0 to A10. The I/O port
addresses of the SMsC FDC37C669 will be mirrored every 800hex in the I/O address
space.
