TA550C Overview
The TL16C550C and the TL16C550CI are functional upgrades of the TL16C550B asynchronous munications element (ACE), which in turn is a functional upgrade of the TL16C450. Functionally equivalent to the TL16C450 on power up (character or TL16C450 mode), the TL16C550C and the TL16C550CI, like the TL16C550B, can be placed in an alternate FIFO mode. This relieves the CPU of excessive software overhead by buffering...
TA550C Key Features
- Programmable Auto-RTS and Auto-CTS
- In Auto-CTSMode, CTS Controls Transmitter
- In Auto-RTS Mode, RCV FIFO Contents and Threshold Control RTS
