External Strobe Register

Accessing the External Strobe Register location generates an active low
signal at the EXTSTROBE* output of the I/O connector. This signal has
a minimum low time of 500 nsec. The EXTSTROBE* pulse is useful
for several applications, including generating external general-purpose
triggers and latching data into external devices, for example, from the
digital output port.
