Section 28 Serial Communication Interface with FIFO/IrDA Interface (SCIF/IrDA)
28.5.2
Figure 28.22 shows a block diagram of the infrared data communication interface.
The infrared data communication interface selects whether serial communication data for the
SCIF2 channel is modulated/demodulated to the infrared data for transmission or reception.
When the IRMOD bit in SCSMRIR is 1, the modulated/demodulated IrDA data is input/output
from the SCIF2_TXD/SCIF2_RXD pin. When the IRMOD bit in SCSMRIR is 0, the data for the
SCIF2 channel is bypassed to the SCIF2_TXD/SCIF2_RXD pin.
When the LOOP bit in SCSMRIR is set to active, output from the infrared data modulation unit is
directly input to the demodulation unit (for loopback testing).
The selector does not use clocks for its logic. Therefore, the status of the selector after a reset or in
standby depends on only the value of SCSMRIR.
Note: This module can detect short pulses such as chattering in reception, be sure to secure the
shortest pulse width specified by the IrDA standard.
