Synchronous Start Function

Synchronous motion means more than one axis can be started by
a synchronous signal (STA) which could be external or internal
signals. For external signal, users must set move parameters first
for all axes then these axes will wait an extern start/stop command
to start or stop. For internal signal, the start command could be
from a software start function. Once it is issued, all axes which are
in waiting synchronous mode will start at the same time.

The PCI-8144 card suports external start function. When the user
sets the external start by _8144_external_start function for each
axis which the user want to perform external start, then set the
move function for those axes. Thoes axis will start at the same
time when STA signal goes ON.
