10. JTAG Connector

The AX7103 Board reserves a 10Pin JTAG interface for downloading programs to
FPGA QSPI FLASH. Each pin of JTAG interface on the expansion headers is
connected to two diodes and a resistor that provides protection against high and low
voltages. Figure 3-12-1 shows hardware design of JTAG interface.
JTAG connector is standard 10pins connector, the pitch is 2.54mm. Figure 3-10-2
shows the onboard JTAG connectors. Do not hot swap
