Bit 7—IrDA Mode (IRMOD): Selects operation as an IrDA serial communication interface.
Bit 7: IRMOD

Note: * When operation as an IrDA interface is selected, bit 7 (C/A) of the serial mode register
Bit 6—Output Pulse Width Select (PSEL): Selects either 3/16 of the bit length set by bits ICK3 to
ICK0 in the serial mode register (SCSMR), or 3/16 of the bit length corresponding to the selected
baud rate, as the IrDA output pulse width. The setting is shown together with bits 6 to 3 (ICK3 to
ICK0) of the serial mode register (SCSMR).

Note: A fixed clock pulse signal, IRCLK, must be generated by multiplying the P clock by 1/2 N +
Bit 5—IrDA Receive Data Inverse (RIVS): Allows inversion of the receive data polarity to be
selected in IrDA communication.
Bit 5: RIVS

Note: Make the selection according to the characteristics of the IrDA modulation/demodulation
Bits 4 to 0—Reserved: These bits are always read as 0. The write value should always be 0.
