Table 5-76 defines the support for wake-up events when the device is operating as a host. A "defined
wake-up event" refers to an interrupt that is recognized by the PMC in host mode: USB, GPIO, eTSEC,
internal timer, external interrupt or PCI (PME input). Since the device is the host, PME signaling refers to
external agents asserting the PCI_PME input to the device, which is one of the defined wake-up events.

Other (e.g., I C) Same as D1 (Case 6), with the following differences:
- e300 is in Sleep mode;
- the e300 may not be awakened by a decrementer timer interrupt.
Other Not applicable, because the e300, IPIC, and other non-essential
blocks are powered off. Only defined wake-up events can wake the
device from D3Warm (see Case 5).
USB, internal timer, When a defined wake-up event occurs PMC will assert an interrupt to
external interrupt, the e300 (if not masked) which will cause it to wake-up directly (return
TSEC, GPIO to D0). Since PME signaling is disabled (PMCCR1[PME_EN] = 0)
PCI_PME will not be asserted to the host. In this case the host will not
be aware of the device power state change. To support PME signaling,
see case 2.
USB, internal timer, Same as Case 10, except e300 transitions to D0 from nap mode. The
external interrupt, state change is not reported to the host.
TSEC, GPIO

Not applicable It is assumed that in D3Cold VDDC and VDD power supplies are
powered off by the host and PORESET is applied. Wake-up events or
PME signaling is not supported in this case. Returning to D0 implies a
POR reset and a complete initialization of the device.
