System Management TCO Registers (D31:F0)
The TCO logic is accessed via 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, PMBASE + 60h in the PCI configuration space. The following table shows the
mapping of the registers within that 32-byte range. Each register is described in the
following sections.
