Address/Data Bus Connector
The DS26334DK has a connector (J4) to monitor all local bus activity for the design kit. All the signals can be
captured with a high-impedance probe and displayed on an oscilloscope or logic analyzer. Note: If the FPGA
switch (SW5) is in the “OFF” position, the on-board microcontroller will no longer drive any data onto the local bus.
Therefore, the user can now connect the local bus of the DS26334/DS26324 into another system without making
any modifications to the hardware. See
