How to read status pins from 2 L6470 Drivers by single MCU

Hello,

 

I am new in this community so please excuse me if the question was already rises. In my application I am planning to use two stepper drivers L6470PD for different stepper motors but driven from the same MCU. Question is the following: Can I share among those two drivers status lines like: FLAG/BUSY/STCK/STBY/SW and by pulling low the CS line define which driver I wanted to use at this moment? Or I should treat the FLAG/BUSY/STCK/STBY/SW lines dedicated for each individual stepper driver.  So in other words plan to use only 5GPIO for two drivers or 10GPIO pins on MCU. 

 

Thank you very much in advance

Jacek
