2.2.5 JTAG Headers
The headers are provided on the board to isolate the CC3235MOD from the onboard XDS110-based
JTAG emulator. These jumpers are shorted by default when the board is shipped from TI. Figure 5 and
Table 1 are for default configurations, and Figure 8 shows the external emulator connection. To connect
an external emulator, remove the isolation block JTAG jumpers and place the external emulator on the
JTAG IN connector.
