Clear W5500 chip

Hello everybody,

I have a trivial question: How to clear every settings in the chip?

I’m receiving dhcp data and i would like to clear everything in the chip and then set him up.

An effective way would be to perform a hardware reset using the RSTn pin.
All registers turn into their default state with this action.

Hi,
in case of DHCP lease you can change temporarily a mac byte to simulate a different device. Then operate on RST line and/or operate a MR Clear via software. In examples this is made in DHCP and DNS sources where set tx/rx buffers size.
