PME signaling to the host from the D1 state is not likely to be used in
an application. When a defined wake-up event occurs PMC will assert
an interrupt to the e300 (if not masked) which will cause it to wake-up
directly.
To support PME signaling the following sequence should be followed:
When a defined wake-up event occurs in D1 and PME signaling is
enabled (PMCCR1[PME_EN] = 1), PCI_PME will be asserted to the
host. Since the e300 has not been powered off, it will return to D0
(full-on) mode directly. To support PME signaling the e300 should not
continue normal processing until the host has instructed the device to
return to D0. The host would do this by writing
PCIPMCR1[Power_State] = 00b in the PCI config space. This will
cause the PMCCR1[NEXT_STATE] field to become 00b (D0) causing
an interrupt to the e300. The e300 can then respond to the host that is
had returned to D0 by writing PMCCR1[CURRENT_STATE] = 00,
which will then be reflected in PCIPMCR1[POWER_STATE],
indicating to the host that it has returned to D0. Normal processing can
then continue.
Same as D1 state (Case 2), except e300 transitions to Full On mode
from Nap state.
Same as D1 state (Case 2), except e300 transitions to Full On mode
from Sleep mode.
In D3Warm the e300 is powered off. When the wake-up event occurs
e300 does not return to D0 directly. Rather, PCI_PME is asserted to
the host. The host will then instruct the device to return to D0 (writing
PCIPMCR1[POWER_STATE] = 00). This will set
PMCCR1[NEXT_STATE] = 00 and the device will continue to
wake-up. Once awake the e300 should signal to the host that it has
returned to D0 by writing PMCCR1[CURRENT_STATE] = 00b which
will set PCIPMCR1[POWER_STATE] = 00. When the wake-up event
occurs the device wakes to a partially uninitialized state (DDRC, IPIC
etc. will need to be initialized). NOTE: PCI_PME signaled to the host
occurs from D3Warm without powering up the device through the
external power switch.
PME signaling to the host from the D1 state is not likely to be used in
an application.
e300 is in Doze mode. If an e300 interrupt occurs, the e300 will
transition to Full On mode directly. PME signalling to the host can be
supported if desired (see Case 2).
Same as D1 state (Case 6), except e300 transitions to Full On mode
from Nap state.
