5.2.6 SPI Commands
E981.07
5.2.6.1 SENSOR_DATA
The SENSOR_DATA command is used to sample sensor data from the 981.07, and is the only command
which uses the sensor data request/response format. The sampling moment is the first rising SCK edge within
the response frame. If the sensor data within the Manchester decoder changes at the same time then this
sampling is repeated at the second rising SCK edge. Details of this command are defined in section SPI Sensor
Data Request / Response Format.
5.2.6.2 NON_SENSOR_DATA
The NON_SENSOR_DATA command is used write configuration data into the 981.07 configuration registers
and read back status information. Details of this command are defined in section SPI Non Sensor Data Request
/ Response Format.
5.2.6.2.1 LINE_ENABLE
The LINE_ENABLE command is used to activate or deactivate the satellite receiver channels individually. The
command is latched until a subsequent SPI update, reset, or any condition which deactivates the channel, such
as thermal, or over current shutdown. The response indicates the current state (①) of the line activation and the
over temperature status for each channel. By default all satellite channels are disabled.
