Input DATA and SCLK after setting of STB = "L". SCLK is not accepted in the state with STB = "H". Input DATA from D0 to D7 in this order. CLK performs data transmission at the rise edge and latches all data at rise of STB after transmission of all data. All of serial data is reset to "0" with ST = "L". and at the voltage to cut VCC low voltage. Timing to Reflect Serial Data to the Output * PWM mode (Applicable to 3, 4, 5, and 6ch) Type 1: FR and DECAY settings during PWM drive are reflected simultaneously with the STB signal of data latching. * STP mode (Applicable to 1, 2, 3, and 4ch) Type 1: HOLD, RESET, CUT ENABLE settings and reference voltage setting are reflected simultaneously with the STB signal of data latching. Type 2: Forward/reverse (F/R) and excitation mode (MS) settings made during STEP setting are reflected at rise of the next clock of data latching.

The reference voltage to set the output current can be changed over in four stages by the serial data. This is effective for power saving during hold power application of the motor. Set Current Calculation Method IOUT = (reference voltage x set current ratio) /SEN resistance As the reference voltage is variable (0.2V, 0.134V, 0.1V, 0.066V) by the serial data, the output current can be set from the reference voltage and SEN resistance. (Example) The output current as shown below flows when the reference voltage is 0.2V, the set current ratio is 100%, and the SEN resistance is 1. IOUT = 0.2V x 100%/1 = 200mA

With OE (D7) data = "0", the output is turned OFF and becomes high impedance at rise of STB. As the internal logic circuit is operating, however, the position number proceeds while CLK is input. Therefore, with OE (D7) data returned to "1", the level along the position number proceeding with the CLK input is output. With RST (D6)= "0", the output is initialized at rise of STB and the MO output becomes Low. With RST (D6)= "1" subsequently, the position number proceeds at the next CLK input.

Hold state
With HOLD (D5) data = "1", the external CLK data is held as it is in the internal CLK. In the step hold (1) timing as shown above, the (external) CLK is at "L", so that the internal CLK is held at "L." In the step hold (2) timing, the (external) CLK is at "H", so that the internal CLK is held at "H." With HOLD (D5) data = "0", the internal CLK is synchronized with the normal (external) CLK. The output holds the status in the timing of input of step hold. After canceling of step hold, the position No. proceeds in the timing of CLK (rise). As long as the hold status continues, the position No. does not proceed even when (external) CLK is input.

DA converter in IC proceeds by one bit at rise of input clock pulse. D2 (F/R) data causes changeover of CW and CCW modes; the position No. decreases in the CW mode and increases in the CCW mode. When viewed from the 1ch current, the 2ch current is delayed by 90 degree in phase in the CW mode. When viewed from the 1ch current, the 2ch current is delayed by 90 degree in the CCW mode.
