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].

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.
