incoming pulse. If an incoming pulse is detected inside this window this process is
repeated. If the incoming data is a logical 1 (no pulse), the endec returns to the initial state
and waits for the next falling edge. As each falling edge is detected, the endec clock
counter is reset, resynchronizing the endec to the incoming signal. This allows the endec
to tolerate jitter and baud rate errors in the incoming data stream. Resynchronizing the
endec does not alter the operation of the UART, which ultimately receives the data. The
UART is only synchronized to the incoming data stream when a Start bit is received.
All infrared endec configuration and status information is set by the UART control regis-
ters as defined in
To prevent spurious signals during IrDA data transmission, set the
Tx Control 1 Register to 1 to enable the Infrared Encoder/Decoder before enabling the
GPIO Port alternate function for the corresponding pin.
