PCIe to Multi I/O Controller
Subsystem Device ID_Fx (0x0D~0x0C, 0x21~0x20, 0x35~0x34, 0x49~0x48)
Bit
Description
15:0
Subsystem Device ID_Fx.
This field will be loaded into PCIe Configuration Space offset 0x2E (Subsystem Device ID).
Note:
◎For SP related PCIe function, bit15~12 should be set to 0x1.
◎For PP related PCIe function, bit15~12 of “Subsystem Device ID_F2” should be set to 0x2.
◎For SPI related PCIe function, bit15~12 of “Subsystem Device ID_F3” should be set to 0x6.
Hardware Default Value:
0x1000: For all SP function.
0x2000: For “Subsystem Device ID_F2” in PP mode.
0x6000: For “Subsystem Device ID_F3” in SPI mode.
0x7000: For “Subsystem Device ID_F0” in LB mode.
Note: Only “Subsystem Device ID_F0” existed in LB mode and if the function has been disabled this
file should be set to 0x0000.
Power Management Capabilities_Fx (0x0F~0x0E, 0x23~0x22, 0x37~0x36, 0x4B~0x4A)
Bit
Description
0
No Soft Reset.
This field will be loaded into PCIe Configuration Space offset 0x7C (Power Management
Status/Control Register), bit 3.
Hardware Default Value:0x1.
3:1
Maximum Current Required.
This field will be loaded into PCIe Configuration Space offset 0x78 (Power Management
Capabilities Register), bit 24:22.
Hardware Default Value:0x7 (375 mA).
4
D1 Support.
This field will be loaded into PCIe Configuration Space offset 0x78 (Power Management
Capabilities Register), bit 25.
Hardware Default Value:0x1.
5
D2 Support.
This field will be loaded into PCIe Configuration Space offset 0x78 (Power Management
Capabilities Register), bit 26.
Hardware Default Value:0x1.
10:6
PME Support.
This field will be loaded into PCIe Configuration Space offset 0x78 (Power Management
Capabilities Register), bit 31:27. {D3 cold, D3 hot PME, D2 PME, D1 PME, D0 PME}.
Note: Bit10, D3 cold, will be “and” logic operation with the 3.3V AUX detect (GPIO2/A3 pull-up
Aux3.3V).
Hardware Default Value:0x1F.
Note 1: Only “ Power Management Capabilities_F0” existed in LB mode.
Note 2: This field should be set to 0x0000 if this function is disabled.
