DRV8889-Q1: DRV8889-Q1

Hi Team, 

I want to know about a outcome .
In CTRL-2 (control register), bit 7 is mapped with DIS_OUT field and it is also mentioned that it is ORed with DRV_OFF Pin. So is it like : 

1 - (Register - DIS_OUT = 0)  ||  (Pin -  DRV_OFF = 0) =  0.
2 - (Register - DIS_OUT = 1)  ||  (Pin -  DRV_OFF = 0) =  1.
3 - (Register - DIS_OUT = 0)  ||  (Pin -  DRV_OFF = 1) =  1.
4 - (Register - DIS_OUT = 1)  ||  (Pin -  DRV_OFF = 1) = 1.

So want to understand that my understanding is correct or it is ANDed instead of ORed. Please clarify on this point.

Thank you in advance .
