5.2.20 Daisy Chain Configuration
Several ripple counter ICs can be connected in daisy chain configuration as shown in Fig. 6. Daisy chain is used to
increase the number of available half bridge to control more than five motors.
In fact only the chip select signal CSB is connected in daisy chain configuration. All other signal are connected in
parallel to all ICs and the μC. The data ready signal DRB is connected wired-or with an external pullup resistor R
