5.3. Hardware Reset Switch (SW3)
(3) in Figure 5.1
This switch (SW3) is available for user application systems using hardware resets.
5.4. CF Card CFOE#/CFRST Select Switch (SW8)
(4) in Figure 5.1
The (SW8) switch on this board configures the CFOE# and CFRST outputs to the CF card interface. The
following Table describes the three configurations available.
If the user application system does not use CF cards, set this to the OFF position. Otherwise, set as C =
