Part Number: DRV8838
In the DRV8838 datasheet, they list the following block diagram for the DRV8838 motor controller:
My question is regarding the EN/PH components in the diagram. My interpretation is that EN and PH have internal pull down resistors. With that assumption in mind, I was looking at the the Device Logic table which has the following:
Question
I'm trying to tell the difference between rows 0 and 1. If my assumption was correct about the pull downs on PH/EN, would the default value be 0? And if so, how can I tell the difference between rows 0 and 1. I am probably wording this wrong, but hopefully the question makes sense. Basically, what is 'x' refer to by default, a 0 or a 1.
If X == 0 by default, then would the following be true:
If sleep is set low(enabled), and PH/EN are set low, you will coast
If sleep is set high(disabled), and PH/EN are set low, you will brake
If sleep is set high(disabled), and PH/EN are set high, you will go in reverse
If sleep is set high(disabled), and PH is low, EN is high, you will go in forward
Thanks!
