JTAG Interface Switches (SW1, SW3–5)
The JTAG switches (SW1, SW3, SW4, and SW5) select between a single-pro-
cessor (one board) and multi-processor (more than one board)
configurations. By default, the four DIP switches are set up for a single
EZ-KIT Lite configuration. See Table 2-11.
The default configuration applies to either a debug agent or an external
emulator, such as the Analog Devices high-performance USB-based emu-
lator (HP-USB) or ICE-100B emulator.
To use an external emulator and multiple EZ-KIT Lites simultaneously in
one CrossCore Embedded Studio (CCES) multi-processor session, set up
the boards as shown in Table 2-12. Attach the boards to each other via
connectors J3 and P8. For two EZ-KIT Lites, no external cables are
required. For three or more EZ-KIT Lites, obtain Samtec JTAG cables
described in “Link Port /JTAG Connectors (J3 and P8)” on page 2-25.
