Step 7Auto Coil Shutdown
As discussed earlier RA5 is used to toggle the use of the automatic shutdown function.
By default, after a motor has stepped, a timer is started, and about 50 ms after all coils for that motor are shut off. And it will resume normal function the next time it is stepped.
If you do not want the motors to shut off, RA5 must be jumped to GND. See diagrams below.
Also the function can be easily turned off in software, if the source code is Purchased
