Global System Parameters

STIME[31:0] – Start time. This 32-bit value can be used to mark

the start time for logging. It is not used internally by the

AS39513, so its format can be application dependent.

DSFID[7:0] – Data storage format identifier. This value is written

by the Write DSFID command and read back as part of the Get

System Info command.

AFI[7:0] – Application family identifier. This value is written by

the Write AFI command and is read back as part of the Get

System Info command.
