PRODUCTION DATA
The UART is a slave peripheral that utilizes the DMA for data transfer or interrupt polling via host CPU. There are five UART modules in the device. All UART modules support IrDA and CIR modes when 48 MHz function clock is used. Each UART can be used for configuration and data exchange with a number of external peripheral devices or interprocessor communication between devices.
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.
