Infrared Encoder/Decoder Control Register Definitions
PS022006-0207
Caution:
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
registers as defined in the beginning in
page 151.
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 corresponding pin.
