Software compatible with 16450 and 16550 UARTs Two modes of operation: UART mode and FIFO mode Configuration capabilities In the FIFO mode transmitter and receiver are each buffered with 16 byte FIFO to reduce the number of interrupts presented to the CPU ...
H16550S为方便重复使用而开发,专为几款莱迪思器件进行了优化,提供具有竞争力的利用率和性能特点。 Features Capable of running all existing 16450 and 16550a software Fully Synchronous design. All inputs and outputs are based on rising edge of clock In FIFO mode, the transmitter and ...
The 16550 is pin-compatible with the 16450 and, by default, runs in 16450 mode. This makes it compatible with software which is not 16550-aware. If your software is 16550-aware, it can turn on a special mode in which the 16550 buffers all data with 16-byte internal buffers. This not...
A standard UART compatible with the TI 16550 device that can run in either 16450-compatible character mode or in 16550-compatible FIFO mode. It does serial-to-parallel conversion on data from modems or other serial devices, and parallel-to-serial convers

OPB 16450 UART Raw UART Interface UART without an OPB interface The raw UART interface (the OPB UART without the OPB IPIF) is nearly identical to the interface described in the National Semiconductor PC16550D UART with FIFOs data sheet (June, 1995), (http://www.national.com/pf/PC...

What I see in the Parker TRM (38.4.3) shows the bring-up to use FCR[0] as “1” when in 16550 mode, or “0” when in 16450 mode. Basically it says the 16450 mode doesn’t use the FIFO queues, but 16550 does. Other bits seem to also be involved, but if not in FIFO mode ...

the UART has been available since the early 1970s. Constantly refined rather than reinvented, it has shown little change over the years in its pin names, function names, or general mode of operation. Modern CMOS UARTs like the National Semiconductor 16550 and the Zilog 8630 are traceable to ...
