2.8.1 Sense-on-Power (SOP) Jumpers
The xWR1843 device can be set to operate in three different modes based on the state of the SOP lines.
These lines are sensed only during boot up of the AWR device. The state of the device is detailed by
Table 4.
The SOP mode is set using switch S1. When the switch position is 'ON', this refers to a 1. When the
switch position is 'OFF', this refers to a 0.
