6.2.3.4.2 Logical Device Configuration Registers
Use to access the registers that are assigned to each logical unit. The Super IO supports two
logical units and has two sets of logical device registers. The two logical devices are UART1
(Logical Number 4) and UART2 (Logical Number 5). A separate set (bank) of control and
configuration registers exists for each logical device and is selected with the Logical Device
Number Register. The INDEX PORT is used to select a specific logical device register. These
registers are then accessed through the DATA PORT. The Logical Device registers are accessible
only when the device is in the Configuration state.
