System Management TCO Registers
(D31:F0)
The TCO logic is accessed through registers mapped to the PCI configuration space
(Device 31:Function 0) and the system I/O space. For TCO PCI Configuration registers,
see LPC Device 31:Function 0 PCI Configuration registers.
TCO Register I/O Map
The TCO I/O registers reside in a 32-byte range pointed to by a TCOBASE value, which
is, ACPIBASE + 60h in the PCI config space. The following table shows the mapping of
the registers within that 32-byte range. Each register is described in the sections
below.

Corresponds to the byte enables, as would be defined by the
PCI C/BE# signals on the PCI bus (even though it may not be
a real PCI cycle). The value is latched based on SMI# going
active.
