DUART

DμART bridge to APB, AHB, AXI bus, it is a soft core of a Universal Asynchronous Receiver/Transmitter (UART). It performs serial-to-parallel conversion on data characters received from a peripheral device or MODEM, and parallel-to-serial conversion on data characters received from the CPU. The CPU can read the complete status of the UART at any time during the functional operation. The reported status information includes the type and condition of the transfer operations performed by the UART, as well as any error conditions (overrun, framing). The DμART includes a programmable baud rate generator that is capable of dividing the timing reference clock input by divisors of 1 to (2¹⁶-1), and producing 16 × clocks for driving internal transmitter logic. Provisions are also included to use this 16 × clock to drive the receiver logic. The DμART has a processor-interrupt system. Interrupts can be programmed according to your requirements, minimizing the computing required to handle the communication link. The core is perfect for applications where the UART Core and microcontroller are clocked by the same clock signal and are implemented inside the same ASIC or FPGA chip, as well as for standalone implementation, where several UARTs are required to be implemented inside a single chip and driven by some off-chip devices.
