Figure 73. Infrared Data Reception
Because of the inherent sampling of the received IR_RXD signal by the bit rate clock,
some jitter can be expected on the first bit in any sequence of data. All subsequent bits in
the received data stream are a fixed 16-clock periods wide.
All Infrared Endec configuration and status information is set by the UART control regis-
ters as defined beginning on

To prevent spurious signals during IrDA data transmission, set the IREN
bit in the UARTx Control 1 register to 1 to enable the Infrared Encoder/
Decoder before enabling the GPIO Port alternate function for the corre-
sponding pin.
