AcpiPm1CntBlkHi - RW – 8 bits - [PM_Reg: 23h]
Bits Default
AcpiPmTmrBlkLo - RW – 8 bits - [PM_Reg: 24h]
Bits Default
0 0b
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].
AcpiPmTmrBlkHi - RW – 8 bits - [PM_Reg: 25h]
Bits Default
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].
CpuControlLo - RW – 8 bits - [PM_Reg: 26h]
Bits Default
2:0 000b
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.
CpuControlHi - RW – 8 bits - [PM_Reg: 27h]
Bits Default
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].
AcpiGpe0BlkLo - RW – 8 bits - [PM_Reg: 28h]
Bits Default
1:0 00b
7:2 00h These bits 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.
AcpiGpe0BlkHi - RW – 8 bits - [PM_Reg: 29h]
Bits Default
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].
