JTAG interface
All deRFarm7 variants are programmable over JTAG interface (TDI, TDO, TCK, TMS). The
radio module contains all necessary pull-up resistors onboard. Use the pin configuration
shown in Figure 25 to connect the radio module to a suitable ARM programmer like the
SEGGER SAM-ICE.

9. Debugging and tracing
Debugging and tracing of the radio module is possible with the RS232-Level-Shifter. This
component is offered by dresden elektronik ingenieurtechnik gmbh. The used pin connection
to connect the radio module to a suitable debug and trace hardware is shown in Figure 26.
