4.2 Switches
The CDB5364 Evaluation Board switches are used for setting speed modes and format protocols and for
resetting devices to their default state. The switch functions are described in
Table 2 .
.
Table 2. CDB5364 Switches
4.3 User Configuration Jumpers
The CDB5364 Evaluation Board jumpers are used for signal routing as shown in Table 3
.
Table 3. User Jumpers
4.4 Reserved Factory Programming Jumpers
The CDB5364 Evaluation Board has two reserved headers, J15 and J8, that are used to factory program
the Cygnal
® 8051 microprocessor and the Xilinx® FPGA so that the FlexGUI interface operates correctly.
Caution! Do not apply power or shorts to these two jumpers as device damage could occur.
