• IrE bit (IrDA enable)
Selects the SCI3_2 I/O pin function between the usual serial function and IrDA function.
• IrCK[2:0] bit (IrDA clock select 2 to 0)
Sets the high pulse width for IrTXD output pulse encoding when the IrDA function is
• IrTXINV bit (IrTX data polarity inversion)
Sets to invert the logic level of the IrTXD output. When inversion is specified, the high pulse
width set with IrCR[2:0] is handled as low pulse width.
• IrRXINV bit (IrRX data polarity inversion)
Sets to invert the logic level of the IrRXD input. When inversion is specified, the high pulse
width set with IrCR[2:0] is handled as low pulse width.
