6300ESB I/O Controller Hub
There are 12 registers in the UART. These registers share eight address locations in the
I/O address space.
base address. Note that the state of the Divisor Latch Bit (DLAB), which is the MOST
significant bit of the Serial Line Control Register, affects the selection of certain of the
UART registers. The DLAB bit must be set high by the system software to access the
Baud Rate Generator Divisor Latches.
