2.9.2 Sense On Power (SOP) Jumpers (J17, J18, J20)

The AWR2E44PEVM 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 AWR2E44P device. The state of the device is described in Table 2-9.

A closed jumper refers to a ‘1’ and open the jumper refers to a ‘0’ state of the SOP signal going to the AWR2E44P device.

Note: The SOP[2:0] pins can also be controlled via the on-board FTDI. In this case the FTDI settings would override the jumper settings.
