AcpiPm1CntBlkHi - RW – 8 bits - [PM_Reg: 23h]
Field Name Bits Default Description
AcpiPm1CntBlkHi register.
AcpiPmTmrBlkLo - RW – 8 bits - [PM_Reg: 24h]
Field Name Bits Default Description
Reserved 0 0b
AcpiPmTmrBlkLo 7:1 00h These bits define the least significant byte of the 16 bit I/O
base address of the ACPI power management Timer block.
Bit 1 corresponds to Addr[1] and bit 7 corresponds to Addr[7].
AcpiPmTmrBlkLo register.
AcpiPmTmrBlkHi - RW – 8 bits - [PM_Reg: 25h]
Field Name Bits Default Description
AcpiPmTmrBlkHi 7:0 00h These bits define the most significant byte of the 16 bit I/O
base address. Bit 0 corresponds to Addr[8] and bit 7
corresponds to Addr[15].
AcpiPmTmrBlkHi register.
CpuControlLo - RW – 8 bits - [PM_Reg: 26h]
Field Name Bits Default Description
Reserved 2:0 000b
CpuControlLo 7:3 00h These bits define the least significant byte of the 16 bit I/O
base address of the ACPI power management CPU Control
block. Bit 3 corresponds to Addr[3] and bit 7 corresponds to
Addr[7]. Addr[2:0] are ignored because this register block is 6
byte long.
CpuControlLo register.
CpuControlHi - RW – 8 bits - [PM_Reg: 27h]
Field Name Bits Default Description
CpuControlHi 7:0 00h These bits define the most significant byte of the 16 bit I/O
base address. Bit 0 corresponds to Addr[8] and bit 7
corresponds to Addr[15].
CpuControlHi register.
AcpiGpe0BlkLo - RW – 8 bits - [PM_Reg: 28h]
Field Name Bits Default Description
Reserved 1:0 00b
AcpiGpe0BlkLo 7:2 00h These bi ts define the least significant byte of the 16 bit I/O
base address of the ACPI power management General
Purpose Event block. Bit 2 corresponds to Addr[2] and bit 7
corresponds to Addr[7]. Addr[1:0] are ignored because this
register block is 4 byte long.
AcpiGpe0BlkLo register.
AcpiGpe0BlkHi - RW – 8 bits - [PM_Reg: 29h]
Field Name Bits Default Description
AcpiGpe0BlkHi 7:0 00h These bits define the most significant byte of the 16 bit I/O
base address. Bit 0 corresponds to Addr[8] and bit 7
corresponds to Addr[15].
AcpiGpe0BlkHi register.
