The ENC28J60 may be commanded to power-down
via the SPI interface. When powered down, it will no
longer be able to transmit and receive any packets.
To maximize power savings:
1.
2.
3.
4.
5.
In Sleep mode, all registers and buffer memory will
maintain their states. The ETH registers and buffer
memory will still be accessible by the host controller.
Additionally, the clock driver will continue to operate.
The CLKOUT function will be unaffected (see
Section 2.3 “CLKOUT Pin”).

When normal operation is desired, the host controller
must perform a slightly modified procedure:

After leaving Sleep mode, there is a delay of many
milliseconds before a new link is established (assuming
an appropriate link partner is present). The host
controller may wish to wait until the link is established
before attempting to transmit any packets. The link

interrupt may be used if it is enabled. See
