Silicon Laboratories Si4704 Series Programming Manual page 251

Table 49 provides an example for the WB Receiver. The table is broken into three columns. The first column lists
the action taking place: command (CMD), argument (ARG), status (STATUS) or response (RESP). For
SET_PROPERTY commands, the property (PROP) and property data (PROPD) are indicated. The second column
lists the data byte or bytes in hexadecimal that are being sent or received. An arrow preceding the data indicates
data being sent from the device to the system controller. The third column describes the action.
Note that in some cases the default properties may be acceptable and no modification is necessary. Refer to
Section "5. Commands and Properties" for a full description of each command and property.
