• Manufacturer Part Number: HD6412320
• Description: Renesas 16-Bit Single-Chip Microcomputer H8S Family H8S-2300 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

14.1
The chip is equipped with a serial communication interface (SCI) that can handle both
asynchronous and synchronous serial communication. A function is also provided for serial
communication between processors (multiprocessor communication function).
14.1.1
SCI features are listed below.
• Choice of asynchronous or synchronous serial communication mode
Asynchronous mode
⎯ Serial data communication executed using an asynchronous system in which
⎯ Serial data communication can be carried out with standard asynchronous communication
⎯ A multiprocessor communication function is provided that enables serial data
⎯ Choice of 12 serial data transfer formats
⎯ Receive error detection: Parity, overrun, and framing errors
⎯ Break detection: Break can be detected by reading the RxD pin level directly in case of a
Synchronous mode
⎯ Serial data communication synchronized with a clock
⎯ Serial data communication can be carried out with other chips that have a synchronous
⎯ One serial data transfer format
⎯ Receive error detection: Overrun errors detected
synchronization is achieved character by character
chips such as a Universal Asynchronous Receiver/Transmitter (UART) or Asynchronous
Communication Interface Adapter (ACIA)
