Figure 2-1 The JTAG configuration scheme
Figure 2-2 The JTAG Switch for MAX10 FPGA and RISC-V
shows the factory settings of the SW2. The SW2.1 position is used for enable/disable
the MAX 10 FPGA in the JTAG chain. When set to ON, the MAX10 FPGA will appear in the
JTAG chain of T-Core. SW2.2 is the JTAG chain switch for RISC-V applications. If it is turned off,
the application will not appear in the JTAG chain. For more information about the RISC-V
application, please refer to section 3.5 for more information.
