92 / 107 page  PI7C8150B ASYNCHRONOUS 2-PORT PCI-TO-PCI BRIDGE Page 92 of 107 April 2015 – Revision 2.1 14.1.50 CAPABILITY ID REGISTER – OFFSET DCh Bit Function Type Description 7:0 Enhanced Capabilities ID R/O Read as 01h to indicate that these are power management enhanced capability registers. 14.1.51 NEXT ITEM POINTER REGISTER – OFFSET DCh Bit Function Type Description 15:8 Next Item Pointer R/O Points to slot number register (B0h). 14.1.52 POWER MANAGEMENT CAPABILITIES REGISTER – OFFSET DCh Bit Function Type Description 18:16 Power Management Revision R/O Read as 001 to indicate the device is compliant to Revision 1.0 of PCI Power Management Interface Specifications. 19 PME# Clock R/O Read as 0 to indicate PI7C8150B does not support the PME# pin. 20 Auxiliary Power R/O Read as 0 to indicate PI7C8150B does not support the PME# pin or an auxiliary power source. 21 Device Specific Initialization R/O Read as 0 to indicate PI7C8150B does not have device specific initialization requirements. 24:22 Reserved R/O Read as 0 25 D1 Power State Support R/O Read as 0 to indicate PI7C8150B does not support the D1 power management state. 26 D2 Power State Support R/O Read as 0 to indicate PI7C8150B does not support the D2 power management state. 31:27 PME# Support R/O Read as 0 to indicate PI7C8150B does not support the PME# pin. 14.1.53 POWER MANAGEMENT DATA REGISTER – OFFSET E0h Bit Function Type Description 1:0 Power State R/W Indicates the current power state of PI7C8150B. If an unimplemented power state is written to this register, PI7C8150B completes the write transaction, ignores the write data, and does not change the value of the field. Writing a value of D0 when the previous state was D3 cause a chip reset without asserting S_RESET_L 00: D0 state 01: not implemented 10: not implemented 11: D3 state Reset to 0 7:2 Reserved R/O Read as 0 8 PME# Enable R/O Read as 0 as PI7C8150B does not support the PME# pin. 12:9 Data Select R/O Read as 0 as the data register is not implemented. 14:13 Data Scale R/O Read as 0 as the data register is not implemented. 15 PME status R/O Read as 0 as the PME# pin is not implemented. 15-0048 |
