The CIR mode uses a variable pulse-width modulation (PWM) technique (based on multiples of a programmable t period) to encompass the various formats of infrared encoding for remote-control applications. The CIR logic transmits data packets based on a user-definable frame structure and packet content.
The CIR (UART3 only) includes the following features to provide CIR support for remote-control applications:
