SPRUJ22A November 2021 – March 2023 AWR2944
The AWR2944EVM can be set to operate in different modes based on the state of the SOP [2:0] lines. These lines are sensed ONLY during boot up of the AWR2944 device. The state of the device is described in Table 2-12.
A closed jumper refers to a ‘1’ and open the jumper refers to a ‘0’ state of the SOP signal going to the AWR2944 device.
