19.4.3
The data format of UART frames used for IrDA communication must be specified by the SCIF_0
registers. The UART frame has eight data bits, no parity bit, and one stop bit.
IrDA communication is performed in asynchronous mode, and this mode must also be specified
by the SCIF_0 registers. The sampling rate must be set to 1/16.
When using IrDA, set the SCIF_0 operating clock by setting the CKE1 and CKE0 bits in the serial
control register to 01.
The IrDA communication rate is the same as the SCIF_0 bit rate, which is specified by the
SCIF_0 registers.
For details on SCIF_0 registers, refer to section 18, Serial Communication Interface with FIFO
(SCIF).
