FUNCTION
15
11
PME_SUPPORT
R
PME support. This 5-bit field indicates the power states from which the PCI1620 can assert PME. These
five bits return a value of 00000b by default, indicating that the firmware loading function does not assert
PME.
10
D2_SUPPORT
R
This bit returns a 0 when read, indicating that the function does not support the D2 device power state.
9
D1_SUPPORT
R
This bit returns a 0 when read, indicating that the function does not support the D1 device power state.
8
6
AUX_CURRENT
R
3.3-Vaux auxiliary power requirements. Because this function does not support PME generation from
D3COLD, this field returns 000b when read.
Device specific initialization. This bit returns 0 when read, indicating that the PCI1620 does not require
special initialization beyond the standard PCI configuration header before a generic class driver is able to
use it.
5
DSI
R
4
RSVD
R
Reserved. Returns zero when read.
3
PME_CLK
R
PME clock. This bit returns 0 when read, because the firmware loading function of the PCI1620 does not
support PME generation.
2
0
PM_VERSION
R
Power management version. This field returns 010b, indicating revision 1.1 compatibility.
