Update: GPIOs Configured as Inputs have Pull-ups
When configured as inputs, the Cirrus Logic EP9315 digital I/Os enable software 3.3V pull-ups. Unconnected pins will read a logic high when configured as inputs.
We will post further details (e.g. impedance of the pull-ups) as we receive them from Cirrus Logic. |
