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.
