• Manufacturer Part Number: peb20560
• Description: Dsp Oriented Pbx Controller Doc
• Manufacturer: Infineon Technologies Corporation

The integrated UART is compatible to the standard 16C550A UART, Figure 2-51.
It has the following features:
• Receiver and transmitter are each buffered with 16-byte FIFO’s (in the FIFO mode) to
• Adds or deletes standard asynchronous communication bits (start, stop, and parity) to
• Holding and shift registers eliminate the need for precise synchronization between the
• Independent control of transmit, receive, line status and data set interrupts
• Programmable baud rate generator for 300 Baud to 256 kBaud; it generates the
• Modem control functions (CTS, RTS, DSR, DTR, RI and DCD)
• False start bit detection
• Complete status reporting capabilities
• Fully programmable serial-interface characteristics:
• Tri-state TTL drive capability for bidirectional data bus and control bus
• Line break generation and detection
• Internal diagnostic capabilities:
• Fully prioritized interrupt system controls
