Stepper motors and drives, what is full step, half step and microstepping?

hey, i have a driver with two pins that i don't know what is, one pin is H/F step that you explained so i assume that if it's disconnected it means Full step or Half step i don't know yet, and the other pin is called "Power Down" can you help me with that? what it is and how should i connect it, the driver model is Sanyo Denki PMM-BD-5701-T3

How do you set FULL step mode to 2 or 1 phase on full step. for 28BYJ-48 Stepper Motor with ULN2003
Also how to set for full or half step

Is it possible for a two phase motor move half step 0.9°? or Can a half step or microstepping able to move 0.9°?

@Liu9079 I presume that you are referring to a 200 step, 1.8 deg stepper motor. Half stepping will indeed move 0.9 degrees but this happens because energising sequence of the windings. Half and micro-stepping reduces the overshoot and vibration not the positional accuracy If the power is removed then the motor will want to jump to the nearest full step position. So positioning to 0.9 degrees isn't possible if the motor has the power removed. Remember steppers are open loop, if you want positional accuracy then you must close the feedback loop with an encoder.
