13. Read Window from beginning up to (but not including) the Largest Offset.
Largest Offset = First Register of Window + (Largest Window Offset/2).
Example: (Index = 14464).
38273 + (0/2) = 38273.
Read from 38273 up to 38273; therefore, read nothing.
14. Set Window Index to 0. Go to step 12.
Example:
Write the value 0 (0000H) to the Window Index Historical Log 1, Register 38145.
15. Read Window from the beginning up to (but not including) the ending offset.
Ending offset = First Register of Window + (ending Window offset/2).
Example: (Index = 250).
38273 + 64/2 = 38305.
Read from 38272 up to (but not including) 38304; therefore, read 38273 – 38304.
16. Un-pause the log by writing FFFFH to the Window Index.
Example:
Write the value FFFFH to the Window Index for Historical Log 1, Register 38145.

Auto Increment Configuration (Register 39423, 0x099FE)
When read, this register returns the configuration in use by the Auto Increment Log Window, below,
to access logs on this port. When written, this register sets the configuration used by the Auto
Increment Log Window, below, to access logs on this port. Each port accesses a separate, independ-
ent configuration through this register allowing all four ports to access logs with different
configurations.
The least significant byte indicates which log is being accessed. The appropriate values are:
0x000 Historical Log 1
0x001 Historical Log 2
0x002 Sequence of Events State Log
0x003 Sequence of Events Snapshot Log
0x004 Digital Input State Log
0x005 Digital Input Snapshot Log
0x006 Digital Output State Log
0x007 Digital Output Snapshot Log
0x008 Flicker Log
0x009 Waveform Trigger Log
0x00A System Event Log
