Section 16 Serial Communication Interface (SCI, IrDA, and CRC)
16.3.10 Serial Interface Control Register (SCICR)
SCICR controls IrDA operation of SCI_1.
16.3.11 Serial Enhanced Mode Register_0 and 2 (SEMR_0 and SEMR_2)
SEMR_0 and SEMR_2 select the SCI_0 and SCI_2 functions, respectively, and the clock source
in asynchronous mode. The basic clock is automatically specified when the average transfer rate
operation is selected.
