6.3 Connecting the CC Debugger to a Transceiver
The SPI interface on the CC Debugger can be used to interface many of the CCxxxx transceivers and
control them from SmartRF Studio. The transceivers/transmitters/receivers currently supported are:

CC1120

CC1121

CC1125

CC1175

CC110L

CC113L

CC115L

CC2520
Note that the CC Debugger operates as the SPI Master. In a multi master system, it is necessary to
make sure the debugger output signals (DC, DD, CSn, SCLK, MOSI and RESETn) do not interfere
with the other SPI master on the board. The other SPI master would typically be the microcontroller on
the board.
The connection diagrams below show the interconnection between the debugger and the various
supported transceivers.
