Table 21-11. IrDA Baud Rate Error (Continued)
The demodulator is based on the IrDA Receive filter comprised of an 8-bit down counter which is
loaded with the value programmed in IFR. When a falling edge is detected on the RXD pin, the
Filter Counter starts counting down at the CLK_USART speed. If a rising edge is detected on the
RXD pin, the counter stops and is reloaded with IFR. If no rising edge is detected when the
counter reaches 0, the input of the receiver is driven low during one bit time.
Figure 21-34
As the IrDA mode uses the same logic as the ISO7816, note that the FI_DI_RATIO field in FIDI
must be set to a value higher than 0 in order to assure IrDA communications operate correctly.
