S3C44B0X is a universal asynchronous receiver-transmitter unit with two independent asynchronous serial I/O ports, supporting interrupt and DMA modes, with a maximum baud rate of 115.2Kbps. Each UART channel contains 2 16-bit FIFOs for receive and transmit.
The S3C44B0X data sheet provides detailed information on the UART module, including its two independent asynchronous I/O ports, FIFO buffers, and supported communication modes. It outlines register definitions, operation modes, and configuration options for baud rate, parity, stop bits, and flow control.
Key sections cover UART operation, data transmission and reception formats, automatic flow control, modem interface signals, interrupt and DMA request generation, error status handling, baud‑rate generation, loopback testing, and infrared communication mode. This manual is written in Chinese.
