Req. 5.2.1.4: "Command, Configuration, and Data Collection Interface to the Instrument Subsystems"
The SIU FSW shall communicate with the LAT instrument subsystems for the purposes of configuration and retrieval of housekeeping and low rate science data (rate counters), using the custom command and response hardware and software serial data protocols defined in [18] - [23].

Test(s)
003: Narrowband Telemetry Verification
This test shall verify the successful collection, sampling rate, formatting, downlinking, and transformation into user units of housekeeping and low-rate science data, alert telemetry, and diagnostic telemetry. If telemetry content is specific to a particular mode (i.e., boot mode or standard operation mode), this test shall verify the correct content as a function of mode.
007: T&DF, TKR, CAL, and ACD Internal Configuration Test
This test shall verify the ability of the SIU to configure the T&DF,TKR, CAL, and ACD subsystems as desired and read back the necessary configuration information to completely determine each subsystem's configuration.
