DIR
This bit controls direction of motor movement. DIR=1 clockwise DIR=0 counter clockwise.
ST1 ST0
This bits controls step mode of motor movement (Figure 3).

Mini-stepping
10
Half-stepping
11
Full-stepping
SR1 SR0
This bit controls slew rate of bridge switches. See also parameter Table 13
DM2 DM1 DM0
This bits controls decay mode of output current (Figure 3).
000
Slow decay
001
Mixed decay, fast decay until TMD > 4 s
010
Mixed decay, fast decay until TMD > 8 s
011
Mixed decay, fast decay until
current undershoot Tmc =TFT +TCC
100
Auto decay, fast decay without delay time
Auto decay uses mixed decay automatically
to reduce current for next step if required
(see Figure 3 down right).
101
Auto decay, fast decay until TMD > 4 s
110
Auto decay, fast decay until TMD > 8 s
111
Auto decay, fast decay until current
undershoot Tmc
P4 P3 P2 P1 P0
This bits control position of motor, e.g. 00000 step angle
is , 01111 step angle is 180 °.
