E.2 UART PROGRAMMING REFERENCE SECTION
This subsection deals with the registers and parameters required to program an SCC as a
UART. At the end of this subsection is a generic algorithm for programming the SCC.
E.2.1 UART Programming Model
The programming model and memory map for the UART protocol is shown in Table E-2. The
offsets for each SCC are given above each table. Some parameters are common to all pro-
tocols. The UART parameters are shown for those entries that are protocol specific. Table
E-2(b) depicts the general and protocol-specific parameter RAM for each SCC. The SCC
registers are shown in Table E-2(c), and the communications processor registers are shown
in Table E-2(d). Note that reserved bits in registers should be written as zeros.
