this pin and pin 2 (Connector P2, Current Adjust) will proportionately
reduced the current in both windings (1 second after the last positive
going edge of the step clock input).  The amount of current reduction
will depend on the value of the resistor used.

1112 STEP MOTOR CONFIGURATIONS4 Lead Motors 
Step motors can be configured as 4, 6, or 8 leads.  Each configuration requires different
currents.  Shown below are different lead configurations and the procedures to determine
their output current.
6 Lead Motors 
When configuring a 6 lead motor in a half-coil configuration (connected from one end
of the coil to the center tap) use the specified per Phase (or unipolar) current rating to
determine the current adjustment resistor value.  This...

Phase 1&3 of the Step Motor is connected between pins 7 and 8  on connector P2.  Phase
2&4 of the Step Motor is connected between pins 5 and 6 on connector P2.  
Refer to Figure 1 for TYPICAL APPLICATION HOOK-UP
NOTE: The physical direction of the motor with respect to the direction input will
depend on the connection of the motor windings.  To reverse the direction of the motor
with respect
to the direction input, switch the wires on Phase 1 & Phase 3....
