WP76xx_switch_USBHost_function.xlsx (39.9 KB)
We would like to switch the function that WP76xx was operated as USB host or USB function.
In order to support it, we make the attached block diagram.
- How to switch: control GPIO22 and GPIO23, and supply to power SW IC to supply Micro USB IF
- How to recognize function: Check the logic via USB_ID or GPIO25
Please check the attached file as “WP76xx_switch_USBHost_function.xlsx”.
Can this block diagram support to switch either USB Host or USB Function?
