Overview
The DSP Series 2 Cache Query permits the host to check whether the specified file is present in the DSP Series 2 main board and DSP chip cache memory.
This feature is implemented by using query type, Cache File Query 0x18 in the System Configuration Query (0x00B4) message.
The File ID will be passed in the data field of the System Configuration Query message. The result of this query is sent back to the host using the Generic Report (0x0046) message with report type, Cache File Query 0x18.
