• Manufacturer Part Number: h8s-2635
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

Note: The H8S/2635 Group is not equipped with a DTC.
13.1
The chip is equipped with 3 independent serial communication interface (SCI) channels. The SCI
can handle both asynchronous and clocked synchronous serial communication. A function is also
provided for serial communication between processors (multiprocessor communication function).
13.1.1
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

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