UART IC 4, QUART Channel 16 Byte 68-PLCC (24.23x24.23)

Integrated Asynchronous Communications Element
Consists of Four Improved TL16C550 ACEs Plus Steering Logic
In FIFO Mode, Each ACE Transmitter and Receiver Is Buffered With 16-Byte FIFO to Reduce the Number of Interrupts to CPU
In TL16C450 Mode, Hold and Shift Registers Eliminate Need for Precise Synchronization Between the CPU and Serial Data
Up to 16-MHz Clock Rate for up to 1-Mbaud Operation
Programmable Baud Rate Generators Which Allow Division of Any Input Reference Clock by 1 to (216-1) and Generate an Internal 16 × Clock
Adds or Deletes Standard Asynchronous Communication Bits (Start, Stop, and Parity) to or From the Serial Data Stream
Independently Controlled Transmit, Receive, Line Status, and Data Set Interrupts
Fully Programmable Serial Interface Characteristics:
5-, 6-, 7-, or 8-Bit Characters
Even-, Odd-, or No-Parity Bit
1-, 1 1/2-, or 2-Stop Bit Generation
Baud Generation (DC to 1-Mbit Per Second)
False Start Bit Detection
Complete Status Reporting Capabilities
Line Break Generation and Detection
Internal Diagnostic Capabilities:
Loopback Controls for Communications Link Fault Isolation
Break, Parity, Overrun, Framing Error Simulation
Fully Prioritized Interrupt System Controls
Modem Control Functions (CTS\, RTS\, DSR\, DTR\, RI\, and DCD\)
3-State Outputs Provide TTL Drive Capabilities for Bidirectional Data Bus and Control Bus
