MSI Capability Register- R - 32 bits - [PCI_Reg: 80h]
Field Name Bits Default Description
CAP Fixed 17 1b CAP Fixed.
Reserved 26:18 000h
CAP Type 31:27 15h CAP Type.
TMKBC_BaseAddrLow Register- RW - 32 bits - [PCI_Reg: 84h]
Field Name Bits Default Description
Reserved 1:0 00b
Addr64 2 0b Defines whether the address is 32 or 64 bits. When this bit =
1, the address is 64 bits; 0 means 32 bits.
MaskBits10thru8 3 0b Defines whether address bits [10:8] are masked.
1 = Masked
0 = No mask (“masked” means bits 10:8 are don’t care)
MaskBits11thru8 4 0b Defines whether address bits [11:8] are masked.
1 = Masked
0 = No mask
MaskBits12thru8 5 0b Defines whether address bits [12:8] are masked.
1 = Masked
0 = No mask
MaskBits13thru8 6 0b Defines whether address bits [13:8] are masked.
1 = Masked
0 = No mask
TMKBC_BaseAddrLow 31:7 0000000h This register defines the lower 32 bit memory address used
for the TMKBC function.
There are actually four sets of such mapping (each set consists of register 84h, 88h, and 8Ch). The selection is
controlled by PCI register 7Ch, bits [6:5]. 00 = set 0, 01 = set 1, 10 = set 2, 11 = set 3. Register 7C[6:5] SHOULD
BE PROGRAMMED FIRST BEFORE 84h, 88h, AND 8Ch ARE ACCESSED.
TMKBC_BaseAddrHigh Register- RW - 32 bits - [PCI_Reg: 88h]
Field Name Bits Default Description
TMKBC_BaseAddrHig
h
31:0 00000000h This register defines the upper 32 bit memory address used
for the TMKBC function. This register has no meaning if bit 2
of 84h is set to 0.
There are actually four sets of such mapping. The selection
is controlled by PCI register 7Ch, bits [6:5].
00 = Set 0
01 = Set 1
10 = Set 2
11 = Set 3
There are actually four sets of such mapping (each set consists of register 84h, 88h, and 8Ch). The selection is
controlled by PCI register 7Ch, bits [6:5]. 00 = Set 0, 01 = Set 1, 10 = Set 2, 11 = Set 3. Register 7C[6:5] SHOULD
BE PROGRAMMED FIRST BEFORE 84h, 88h, AND 8Ch ARE ACCESSED.
TMKBC_Remap Register- RW - 16 bits - [PCI_Reg: 8Ch]
