RM57L843: Unused inputs on RM57L843

Michael Forster

Part Number: RM57L843

Is there any guidance on what to do with unused inputs on the RM57L843? For example I am not using the Ethernet controller so what should I do with the MII_TX_CLK, MII_RX_DV etc. pins?

Thanks,

Mike

Hell Michael,

Most pins on RM57 device have programmable internal pull-up and pull-down. This internal pull-up/pull-down allows unused I/O pins to be left unconnected.
