Secondly, the Memory Space can be enabled by Application or Driver software, after the Operating
system has started. This can be accomplished by writing a data value to an I/O Space Address which
is decoded by the following J3B Jumper settings. Only one byte of the I/O Space is decoded at this
I/O Address, and the location is Write Only.

Memory Mode to enable the Memory Space address decoding.
2. Writing a data value of 0xA5 will enable the Memory Space, and a data value of 0x5A
will disable the Memory Space. All other data values written will be ignored.
3. When the Memory Space is permanently enabled (when J3C-1 is removed), any data
value written to the “Memory Enable” I/O address will be ignored.
Base Address Decoding
The CTI CANpro/104 board decodes its Base Address setting (in either Memory or I/O Spaces) by
comparing (matching) various Jumper settings with PC/104 Bus Address bits.
If a Jumper is installed, then the corresponding Address Bit will be matched as a logical “1”.
If a Jumper is removed, then the corresponding Address Bit will be matched as a logical “0”.
The matching of Jumper settings to Address bits depends on whether the board is operated in Memory or I/O
Spaces, and whether PeliCAN or BasicCAN mode is selected.
