Data received from the infrared transceiver using the IR_RXD signal through the RXD pin
is decoded by the Infrared Endec and passed to the UART. The UART’s baud rate clock is
used by the Infrared Endec to generate the demodulated signal (RXD) that drives the
UART. Each UART/Infrared data bit is 16-clocks wide.

RXD pin.
Infrared Data Reception
Endec Receiver Synchronization
The IrDA receiver uses a local baud rate clock counter (0 to 15 clock periods) to generate
an input stream for the UART and to create a sampling window for detection of incoming
pulses. The generated UART input (UART RXD) is delayed by 8 baud rate clock periods
with respect to the incoming IrDA data stream. When a falling edge in the input data
stream is detected, the Endec counter is reset. When the count reaches a value of 8, the
UART RXD value is updated to reflect the value of the decoded data. When the count
reaches 12 baud clock periods, the sampling window for the next incoming pulse opens.
The window remains open until the count again reaches 8 (that is, 24 baud clock periods
since the previous pulse was detected), giving the Endec a sampling window of minus four
