When a value other than 0x0FFFF is written to this Register, the index is updated. If the Window
Mode for this log indicates a Paused Mode (0x00000 or 0x00001 in Register 38209), Historical Log
1 is paused, preventing the addition of new records while the log is being accessed. A30-second
timer is initiated on these writes. Should the timer run out (a new index is not written within 30
seconds), Historical Log 1 will be allowed to continue logging.
When a value of 0x0FFFF is written to this Register, it signifies that the port is finished accessing
Historical Log 1, the 30-second timer is canceled and Historical Log 1 will be allowed to continue
logging.
Should multiple ports access the same log simultaneously, the log will be paused while either
30-second timer is running. The log will be allowed to continue logging only when both ports
time-out or write 0x0FFFF to their Index Register.
