How to PowerDown the W5500 ?


I have an Arduino Nano with the W5500 and check every Monday for the current Time over Ethernet. It works but it is not necessary that the Module is running all the Time.
So I want to check the Time and set the Module to Power Down but I can’t find any Example for this Function.

Disable (power down) PHY using CFGPHYR, it can be done without hardware modifications. If you want to power down the whole chip, then it must be performed externally to the chip using its power supply.
