Section 15 Serial Communication Interface (SCI and IrDA)
Description
IrDA Enable
Specifies SCI_2 I/O pins for either normal SCI or IrDA.
0: TxD2/IrTxD and RxD2/IrRxD pins function as TxD2
1: TxD2/IrTxD and RxD2/IrRxD pins function as IrTxD
IrDA Clock Select 2 to 0
These bits specify the high-level width of the clock
pulse during IrTxD output pulse encoding when the
IrDA function is enabled.
