A:SW1 Isolated emulation and UART communication enable switches:
Switch Position 1 – JTAG Enable:
• ON – All signals between the xds100v2 emulation logic and the MCU will be connected. This setting is valid
when the MCU is being debugged or programmed via the on-card xds100v2 emulator.
• OFF – The xds100v2 emulation logic will NOT be connected to the MCU. This setting is valid when the device
will boot from FLASH, boot from a peripheral directly, or when an external JTAG emulator will be used.
Switch Position 2 – ISO UART communication enable:
• ON – The C2000 MCU’s GPIO-28 (and pin 76 of the 180-pin controlCARD connector) will be coupled to the
FTDI’s USB-to-Serial adapter. This allows UART communication to a computer via the FTDI chip. However, in
this position, GPIO-28 will be forced high by the FTDI chip. Functionality of pin 76 of the connector will be
limited.
• OFF – The C2000 MCU will NOT be connected to the FTDI USB-to-Serial adapter. Pin 76 of the 180-pin
controlCARD connector will be directly connected to GPIO-28.
