In CIR mode, the infrared operation functions as a programmable (universal) remote control.
The CIR mode uses a variable 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 user-defined frame structure and packet content.
