Input/Output Address Map
As with all standard PC/104 boards, the Input/Output (I/O) space is addressed by 10 address lines
(SA0-SA9). This allows 2
10
or 1024 distinct I/O addresses. Any add-on modules you install must
therefore use I/O addresses in the range 0-1023 (decimal) or 000-3FF (hex).
The table below lists I/O addresses reserved for the cpuModule.
If you add any PC/104 modules or other peripherals to the
system you must ensure they
do not use reserved addresses
listed below, or malfunctions will occur. The exception to
this is if the resource has been released by the user.
