The fields of the PCI Express power management timer register are described in
18.3.10.16 PCI Express PME Time-Out Register (EP-Mode Only)—0x454
The PCI Express PME time-out register, shown in
that the controller uses before re-sending a PME message to the host. If PME is requested by a function
and the host does not clear the associated PME_STAT bit even after this time-out has expired, the PME
message is sent again to the host by the PCI Express controller. This register is supported only for EP
mode.

functions are in a non-D0 power state. The value is calculated as:
The time value must be less than 2 µsec; the default value (0x14D) is 1 µsec for the default clock
frequency of 333 MHz.
Time in value (in PCI Express controller core clock cycles) for entering L0s power state. The
value is calculated as:
The maximum time value is 7 µsec; the default value (0x7CE) is 6 µsec for the default clock
frequency of 333 MHz.

The PME time-out value specifies the interval before PME messages are resent by the controller,
provided the PME_STAT bit in the PCI Express power management status and control register
(offset 0x48) is not cleared by the host. The value for PME_TIMEOUT is specified in terms of
PCI Express controller core clock cycles. The value is calculated as:
The minimum time value is 100 msec; the default value (0x1FC1E20) is 100 msec for the default
clock frequency of 333 MHz.
