●The TL16C550CPTR is an Asynchronous Communications Element relieves the CPU of excessive software overhead by buffering received and transmitted characters. The receiver and transmitter FIFOs store up to 16 bytes including three additional bits of error status per byte for the receiver FIFO. In the FIFO mode, there is a selectable auto-flow control feature that can significantly reduce software overload and increase system efficiency by automatically controlling serial data flow using RTS\ output and CTS\ input signals. It perform serial-to-parallel conversions on data received from a peripheral device or modem and parallel-to-serial conversion on data received from its CPU. The CPU can read the ACE status at any time. The ACE includes complete modem control capability and a processor interrupt system that can be tailored to minimize software management of the communications link.
● Programmable Auto-RTS\ and Auto-CTS\
● In Auto-CTS\ mode, CTS\ controls transmitter
● In Auto-RTS\ mode, RCV FIFO contents and threshold control RTS\
● Capable of running with all existing TL16C450 software
● After reset, all registers are identical to the TL16C450 register set
● Up to 16MHz clock rate for up to 1Mbaud operation
● Independent Receiver Clock Input
● Transmit, receive, line status and data set interrupts independently controlled
● False-start bit detection
