Value that is loaded into the timer each time the TCO_RLD register is written. Values of 0h
be ignored and should not be attempted. The timer is clocked at approximately 0.6 seconds, and
this allows timeouts ranging from 2.4 seconds to 38 seconds.
Data Register 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.
Data Register 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.
