7.2. Registers in Memory-Mapping Mode
Each UART channel has a dedicated 512-byte register block in Memory mode. The register block can be
accessed by the UART Memory Base Address, which is obtained by adding the UART Register Offset to
the content of the Base Address Register 1 (BAR1). The following diagram shows the arrangement of
individual UART register blocks.
