Note:
IrDA interface
UPSD34xx devices provide an internal IrDA interface that will allow the connection of the
UART1 serial interface directly to an external infrared transceiver device. The IrDA interface
does this by automatically shortening the pulses transmitted on UART1’s TxD1 pin, and
stretching the incoming pulses received on the RxD1 pin. Reference Figures
When the IrDA interface is enabled, the output signal from UART1’s transmitter logic on pin
TxD1 is compliant with the IrDA Physical Layer Link Specification v1.4 (www.irda.org)
operating from 1.2k bps up to 115.2k bps. The pulses received on the RxD1 pin are
stretched by the IrDA interface to be recognized by UART1’s receiver logic, also adhering to
the IrDA specification up to 115.2k bps.
