A read of this register releases the time capture lockout function if it has been enabled. See
CMD
OFFSET Ox24for
additional details. The data read from this offset is meaningless. A write to the
UNLOCK register acts as a secondary time latching strobe. Time is latched in
EVENTO
-
EVENT4.
This feature allows the host to capture two times independently.
