SLWU079D March 2012 – April 2016
The TSW1405 has provisions for four jumpers which are normally not installed. Each jumper has one post connected to an FPGA input and a pull up resistor while the other post connects to ground. These jumpers are reserved for possible future use for setting options to the FPGA or for possible output connections from the FPGA.
The TSW1405 also has an optional 6-pin header for connection to the JTAG port of the FPGA, but the JTAG header may not be installed. The JTAG port would allow the use of an FPGA programming pod, but is not necessary since the FPGA firmware is downloaded from the PC at runtime.
