!Circuit operation  
1. Driver control terminal 1 and 2 (pin22 and pin23)  
All the drivers and spindle-drive braking mode can be switched on/off by inputting combinations of H-level signal  
(higher than 2V) and L-level signal (lower than 0.5V) to these terminals.

4)  
1) Standby mode  
The IC is brought into standby state, and its power dissipation can be limited.  
2) Drivers muting  
All the output channels except the loading are muted and their outputs are turn off.
