Decoding Example:
• Event type 0x01: System event
• Event ID 0x15: DSP (reported) status, decimal 21.
• Event time 0x5438F571: 11 October 2014 10:16:33 (local time)
• Event time 0x0096: 15 ms (150 x 0.1 ms), so 10:16:33:015
• Event Data: up to 4 bytes of pre-event data, 4 bytes of post-event data
• For a DSP (reported) status event all 8 bytes are used.
• Pre-event status is: 0x00000000
• Post-event status is: 0x00004000
Analysis: bit 14 of the DSP status has changed from 0 to 1 (meaning a link or
auxiliary module error has been detected).
