16.3 Register Descriptions
This section contains a detailed description of each register and its specific function.
Flowcharts in Section 16.5.6, “Programming,” describe basic UART module programming.
The operation of the UART module is controlled by writing control bytes into the
appropriate registers. Table 16-1 is a memory map for UART module registers.
