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

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
