Hi everyone again,
here I am triying to reduce current consumption in NGW100.
I'm planning to do an audio player prototype, and since most of the time the eth ports are not being used, I would like to shut them down.
I saw there is a powerdown bit in one of the PHY registers, is it set when the interface is down? or does anyone know a way to force it so that I get less mA consumption?
Of course, disconnecting the RJ45 jack saves a lot of power (about 25mA here), but I wanted to know if there is something else that could be done.
EDIT: is there a way to put the AVR into sleep mode while in linux, to wake up again by some interrupt?
