IrDA Register
The IrDA register allows selection of IrDA SIR- and MIR-compliant pulse shaping at the TX_ and RX_ interfaces. It also
allows inversion of the TX_ and RX_ logic, independently of whether IrDA is enabled or not.
Bits 7, 6: No Function
Bit 5: TxInv
Set the TxInv bit high to invert the logic at the TX_ output. This is independent of IrDA operation.
Bit 4: RxInv
Set the RxInv bit high to invert the logic state at the RX_ input. This is independent of IrDA operation.
Bit 3: MIR
Set the MIR and IrDAEn bits high to select IrDA 1.1 (MIR) with 1/4 period pulse widths.
Bit 2: RTSInvert
Set the RTSInvert bit high to invert the RTS output.
Bit 1: SIR
Set the SIR bit and the IrDAEn bits high to select IrDA 1.0 pulses (SIR) with 3/16th period pulses.
Bit 0: IrDAEn
Set the IrDAEn bit high so that IrDA compliant pulses are produced at the TX_ output and the MAX14830 receiver
expects such pulses at its Rx input. If IrDA[0] is set to low (default), normal (non-IrDA) pulses are generated and
expected at the receiver. IrDAEn must be used in conjunction with the SIR, ShortIR, or MIR select bits.
