Note 3.16 The PME interrupt status bit on the INT_STS register (PME_INT) is set regardless of the
A write to the BYTE_TEST register, regardless of whether a carrier was detected, will return the
LAN9220 to the D0 state and will reset the PM_MODE field to the D0 state. As noted above, the host
is required to check the READY bit and verify that it is set before attempting any other reads or writes
of the device. Before the LAN9220 is fully awake from this state the EDPWRDOWN bit in register 17
of the PHY must be cleared in order to wake the PHY. Do not attempt to clear the EDPWRDOWN bit
until the READY bit is set. After clearing the EDPWRDOWN bit the LAN9220 is ready to resume
normal operation. At this time the WUPS field can be cleared.
