I have been looking for information about the OC (Over Current) and USB Power Enable functionality in the iMX6.
I have a USB Host interface, with a external USB power switch with an "over current" output which is active low and a Enable input which is active low.
The Freescale evaluation board, (Smart Device Platform) have a similar device, but with OC output active low and USB Power EN active high.
So, can I change the USB_H1_PWR_EN signal to support the active low input of my USB power switch?
Can someone explain how thiese signals (USB_H1_PWR_EN, USB_H1_OC) function in the device.
(I have looked through Freescale documentation...)
PS. I would like to keep the USB power switch that I currently use. I know it is possible to get a version with active high EN input.
