70 / 159 page  Classic PCI Configuration Space 60 April 2007 Revised October 2008 SCPS155C 4.24 I/O Base Upper 16-Bit Register This read/write register specifies the upper 16 bits of the I/O base register. See Table 4−15 for a complete description of the register contents. PCI register offset: 30h Register type: Read/Write Default value: 0000h BIT NUMBER 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 RESET STATE 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Table 4−15. I/O Base Upper 16-Bit Register Description BIT FIELD NAME ACCESS DESCRIPTION 15:0 IOBASE RW I/O base upper 16 bits. Defines the upper 16 bits of the lowest address of the I/O address range that determines when to forward I/O transactions downstream. These bits correspond to address bits [31:20] in the I/O address. The lower 20 bits are assumed to be 00000h. 4.25 I/O Limit Upper 16-Bit Register This read/write register specifies the upper 16 bits of the I/O limit register. See Table 4−16 for a complete description of the register contents. PCI register offset: 32h Register type: Read/Write Default value: 0000h BIT NUMBER 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 RESET STATE 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Table 4−16. I/O Limit Upper 16-Bit Register Description BIT FIELD NAME ACCESS DESCRIPTION 15:0 IOLIMIT RW I/O limit upper 16 bits. Defines the upper 16 bits of the top address of the I/O address range that determines when to forward I/O transactions downstream. These bits correspond to address bits [31:20] in the I/O address. The lower 20 bits are assumed to be FFFFFh. 4.26 Capabilities Pointer Register This read-only register provides a pointer into the PCI configuration header where the PCI power management block resides. Since the PCI power management registers begin at 50h, this register is hardwired to 50h. PCI register offset: 34h Register type: Read-only Default value: 50h BIT NUMBER 7 6 5 4 3 2 1 0 RESET STATE 0 1 0 1 0 0 0 0 |
