Only the registers listed in Table 24-109 are used for the CIR function.
Table 24-109 CIR Mode Register Overview (1) REGISTER_NAME(CIR) notation indicates that the register exists for other functions (IrDA or UART), 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 CIR function.
