16 / 40 page  LV8726TA www.onsemi.com 16 Summary of System Mode Control (ST, OE, RST) The following table shows the summary of the system mode control function with ST, OE and RST pins. Table 3: System Mode Control ST OE RST Output Step position L * * High impedance - H H H High impedance Home position H H L High impedance Based on STEP signal H L H Active Home position H L L Active Based on STEP signal Step Clock Signal Input Pin (STEP) A rising edge of the step clock signal at STEP pin advances the step position of the stepper motor by advancing the electrical angle of the excitation current for the motor coils. The number of steps for 90 degree of an electrical cycle (i.e. resolution) is determined by the register bits which are accessible through the serial interface. Table 4: Step Position Control by STEP pin ST STEP Operating mode L * Standby mode H Advancing step position H step position is kept Table 5: Micro Step Resolution Setting Bit setting (D1=0, D0=0) Micro step resolution: STEPMODE Home position 1ch current 2ch Current D5 D4 D3 D2 0 0 0 0 1/2 100% 0% 0 0 0 1 1/4 100% 0% 0 0 1 0 1/8 100% 0% 0 0 1 1 1/16 100% 0% 0 1 0 0 1/32 100% 0% 0 1 0 1 1/64 100% 0% 0 1 1 0 1/128 100% 0% 0 1 1 1 1/3 100% 0% 1 0 0 0 1/6 100% 0% 1 0 0 1 1/12 100% 0% 1 0 1 0 1/36 100% 0% 1 0 1 1 1/5 100% 0% 1 1 0 0 1/10 100% 0% 1 1 0 1 1/20 100% 0% 1 1 1 0 1/50 100% 0% 1 1 1 1 1/100 100% 0% Rotational Direction Control Pin (FR) FR controls the progression of the electrical angle of the motor. When FR is Low, the direction is clockwise, and when FR is High, direction is counter-clockwise. Table 6: Direction Control by FR pin FR Operating mode Low Clockwise (CW) High Counter-clockwise (CCW) Figure 25 shows an example of the direction change with FR pin. Figure 25. Example of Direction Reversal Position Monitor Output Pin (MO) The active low, open drain pin MO indicates the home position of the motor. An example of pin MO waveform is as shown Figure 44 and Figure 45 of page 33 and 34.
