Application Operation Input Data
Data are input on the rising edge of CLK. Every input of a data string (16-bit) requires input of the Strobe signal.
For the input conditions, see page 10, Functions.
We recommend Mixed Decay Mode (37.5%) as Decay Mode.
Set torque to 100%. Same as 1-2 phase excitation (typ. A) in the previous section, power dissipation can be reduced
by changing 0% level to 10% or −10%.
