Short Desc. : D16450: Configurable UART
Overview :
The D16450 is a soft Core of a Universal Asynchronous Receiver/Transmitter (UART) functionally identical to the TL16C450. D16450 performs serial-to-parallel conversion on data characters received from a peripheral device or a 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.
Features : - Software compatible with 16450 UART
- Configuration capability
- Separate configurable BAUD clock line
- Majority Voting Logic
- Adds or deletes standard asynchronous communication bits (start, stop, and parity) to or from the serial data
- In UART mode receiver and transmitter are double buffered to eliminate a need for precise synchronization between the CPU and serial data
- Independently controlled transmit, receive, line status, and data set interrupts
- False start bit detection
- 16 bit programmable baud generator
- MODEM control functions (CTS, RTS, DSR, DTR, RI, and DCD)
