power state with all internal functions disabled, except for the MII management interface. To properly exit this mode and
return to normal PHY operation, use the following programming sequence:
1. Disable Slow Oscillator Mode by writing a zero to register 11h, bit 5.
2. Disable Power Down Mode by writing a zero to register 0h, bit 11.
3. Initiate software reset by writing a one to register 0h, bit 15.
Reference Circuit for Power and Ground Connections
The KSZ8051MNL/RNL is a single 3.3V supply device with a built-in regulator to supply the 1.2V core. The power and
ground connections are shown in the following figure and table for 3.3V VDDIO.
