TCO Data In Value — R/W. This data register field is used for passing commands from
the OS to the SMI handler. Writes to this register will cause an SMI and set the
SW_TCO_SMI bit in the TCO1_STS register (D31:F0:04h).
TCO Data Out Value — R/W. This data register field is used for passing commands
from the SMI handler to the OS. Writes to this register will set the TCO_INT_STS bit in
the TCO_STS register. It will also cause an interrupt, as selected by the TCO_INT_SEL
bits.
