DS90UB927/928 how to setting the GPIO

Vincent Hsieh

Dear Sir,

We use the IMX6 platform.
Below is our flow.
IMX6 GPIO(output) ->DS90UB927 GPIO1/GPIO0(forward channel input, local ) -> DS90UB928 GPIO1/GPIO0(forward channel output, remote ) -> LCD backlit.
Could you let us know how to setting it?

Here are the register settings for configuring GPIO between 927 and 928, which can be found in the datasheet ( page 27).

Is this what you're looking for?
