2.3 Muxing Scheme for Multiple Sources
There are multiple sources as shown in Figure 2-4 such as 40 pin LP/BP, DCA1000 EVM, onboard FTDI and
XDS110 that can control the Radar front-end chip in the starter kit. This is done with the help of mux scheme
implemented on the MMWAVEICBOOST. Follow the switch settings as shown in
Table 2-1 to avoid the conflicts.
The most used configuration is the default position.
