Only the registers listed in Table 24-107 are used for the UART function.
Table 24-107 UART Mode Register Overview (1) REGISTER_NAME(UART) notation indicates that the register exists for other functions (IrDA or CIR), but fields have different meanings for other functions (described separately in
Section 24.3.6,
UART/IrDA/CIR Register Manual).
(2) REGISTER_NAME[m:n] notation indicates that only register bits numbered m to n apply to the UART function.
