The Asynchronous Serial Interface (ASI) is a serial port that frames (synchronizes) each
character of information with start and stop elements. Parameters control transfer speed (using
a dedicated baud rate generator), character length, number of stop bits, and use of parity.
• Built-in baud rate generator
• Character length: 7 or 8 bits
• Stop bits: 1 or 2
• Parity: none, odd, or even
• Error detection for receiving: parity, framing, and overrun errors
• Full duplex operation
Overview
Block Diagram
Figure 8.1 gives a block diagram for the Asynchronous Serial Interface (ASI), which includes
the following components:
- Baud rate generator (ASBGEN), which controls transfer speed
- ASI Control Register (ASICON), which controls transmission and reception
- ASI Buffer Register (ASBUF), interface to two buffers which hold transmitted and
- ASI Status Register (ASIST), which indicates transfer status
- Shift registers for transmission and reception
