14.10 Configuration Registers

The registers listed in the Configuration Register Summary table are for a single instance of the UART. The addresses

of each register listed in this table are defined as a relative offset to the host “Base Address” defined in the Configuration

Each Configuration register access through the Host Access Port is via its LDN and its Host Access Port Index. EC

access is a relative offset to the EC Base Address.
