Description
IrDA Enable
Specifies normal SCI mode or IrDA mode for
SCI_0 input/output.
0: Pins TxD0/IrTxD and RxD0/IrRxD function as
1: Pins TxD0/IrTxD and RxD0/IrRxD function as
IrDA Clock Select 2 to 0
Specifies the high pulse width in IrTxD output
pulse encoding when the IrDA function is enabled.
000: Pulse width = B × 3/16 (3/16 of bit rate)
001: Pulse width = φ/2
010: Pulse width = φ/4
011: Pulse width = φ/8
100: Pulse width = φ/16
101: Pulse width = φ/32
110: Pulse width = φ/64
111: Pulse width = φ/128
IrTx Data Invert
Specifies the logic level of the IrTxD output to be
inverted. When inversion is performed, the high
pulse width specified by bits 6 to 4 becomes the
low pulse width.
0: Transmit data is used as IrTxD output without
1: Transmit data is inverted before used as IrTxD
