• Manufacturer Part Number: HD6412240
• Description: Renesas 16-Bit Single-Chip Microcomputer H8S Family / H8S/2200 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

12.1
The H8S/2245 Group is equipped with a 3-channel serial communication interface (SCI). All three
channels have the same functions. The SCI can handle both asynchronous and clocked
synchronous serial communication. A function is also provided for serial communication between
processors (multiprocessor communication function).
12.1.1
SCI features are listed below.
Choice of asynchronous or clocked synchronous serial communication mode
Asynchronous mode
Clocked Synchronous mode
Serial data communication executed using asynchronous system in which synchronization
is achieved character by character
Serial data communication can be carried out with standard asynchronous communication
chips such as a Universal Asynchronous Receiver/Transmitter (UART) or Asynchronous
Communication Interface Adapter (ACIA)
A multiprocessor communication function is provided that enables serial data
communication with a number of processors
Choice of 12 serial data transfer formats
Data length:
Stop bit length:
Parity:
Multiprocessor bit:
Receive error detection: Parity, overrun, and framing errors
Break detection:
Serial data communication synchronized with a clock
Serial data communication can be carried out with other chips that have a synchronous
communication function
One serial data transfer format
Data length:
Receive error detection: Overrun errors detected

Overview
Features
7 or 8 bits
1 or 2 bits
Even, odd, or none
1 or 0
Break can be detected by reading the RxD pin level directly
in case of a framing error
8 bits
