Note
SOP0 is pulled high when switch is on the OFF position and low when the switch is the ON position.
SOP 1 and 2 are pulled low when the switch is OFF and high when the switch is ON.
In MMWAVEICBOOST mode, the xWR6843AOPEVM is mounted on the MMWAVEICBOOST and the
SOP mode is set by the MMWAVEICBOOST.
4.8 Modular and MMWAVEICBOOST Mode
The IWR6843AOP can be used in modular mode or mounted on the MMWAVEICBOOST for debugging.
4.8.1 Modular Mode
When used in Modular mode, the UART can either be routed to the SICP2015, which displays the data on the
mmWave visualizer, or to other devices connected to the USB interface. The UART data can also be routed to
the CC2642R2F, which transmits data to a wireless device through Bluetooth.
Figure 4-12 shows the setup for
SICP2015. Figure 4-13 shows the setup for CC2642R2F.
