Bits	Name	Access	Function

2	DOCOUNT	Read/write	Write a 1 to this bit to transfer the contents of the
			buffer register to the count and speed registers.
			This causes the corresponding number of steps
			to be performed.

1	SINGLESTEP	Read/write	Write a 1 to this bit to advance the stepper motor
			by one step. The step speed register, step count
			register, and bit 2 are ignored.

0	DIR	Read/write	This bit controls the direction of rotation. The
			actual direction of rotation (clockwise or
			anticlockwise) depends on how the motor is
			wired to the interface module.
