17.4.1.7 CLS—Cache Line Size Register (KT—D22:F3)
Address Offset: 0Ch Attribute: RO
Default Value: 00h Size: 8 bits
This register defines the system cache line size in DWORD increments. Mandatory for
master which use the Memory-Write and Invalidate command.
17.4.1.8 KTIBA—KT IO Block Base Address Register (KT—D22:F3)
Address Offset: 10–13h Attribute: RO, R/W
Default Value: 00000001h Size: 32 bits
17.4.1.9 KTMBA—KT Memory Block Base Address Register (KT—D22:F3)
Address Offset: 14–17h Attribute: RO, R/W
Default Value: 00000000h Size: 32 bits
17.4.1.10 SVID—Subsystem Vendor ID Register (KT—D22:F3)
Address Offset: 2Ch–2Dh Attribute: R/WO
Default Value: 0000h Size: 16 bits
17.4.1.11 SID—Subsystem ID Register (KT—D22:F3)
Address Offset: 2Eh–2Fh Attribute: R/WO
Default Value: 8086h Size: 16 bits
Bit Description
7:0 Cache Line Size (CLS)— RO. All writes to system memory are Memory Writes.
Bit Description
31:16 Reserved
15:3 Base Address (BAR)— R/W. This field provides the base address of the I/O space (8 consecutive
I/O locations).
2:1 Reserved
0 Resource Type Indicator (RTE)— RO. This bit indicates a request for I/O space
Bit Description
31:12 Base Address (BAR)— R/W. This field provides the base address for Memory Mapped I,O BAR.
Bits 31:12 correspond to address signals 31:12.
11:4 Reserved
3 Prefetchable (PF)— RO. This bit indicates that this range is not pre-fetchable.
2:1 Type (TP)— RO. This field indicates that this range can be mapped anywhere in 32-bit address
space.
0 Resource Type Indicator (RTE)— RO. This bit indicates a request for register memory space.
Bit Description
15:0 Subsystem Vendor ID (SSVID) — R/WO. Indicates the sub-system vendor identifier. This field
should be programmed by BIOS during boot-up. Once written, this register becomes Read Only. This
field can only be cleared by PLTRST#.
Note: Register must be written as a DWord write with SID register.
Bit Description
15:0 Subsystem ID (SSID) — R/WO. Indicates the sub-system identifier. This field should be
programmed by BIOS during boot-up. Once written, this register becomes Read Only. This field can
only be cleared by PLTRST#.
Note: Register must be written as a DWord write with SVID register.
