Section 10 Serial Communication Interface
10.1 Overview
The H8/38024 Group is provided with one serial communication interface, SCI3.
Serial communication interface 3 (SCI3) can carry out serial data communication in either
asynchronous or synchronous mode.
10.1.1 Features
Features of SCI3 are listed below.
• Choice of asynchronous or synchronous mode for serial data communication
⎯ Asynchronous mode
Serial data communication is performed asynchronously, with synchronization provided
character by character. In this mode, serial data can be exchanged with standard
asynchronous communication LSIs such as a Universal Asynchronous
Receiver/Transmitter (UART) or Asynchronous Communication Interface Adapter
(ACIA).
There is a choice of 12 data transfer formats.
Data length
Stop bit length
Parity
Receive error detection
Break detection
7, 8, 5 bits
1 or 2 bits
Even, odd, or none
Parity, overrun, and framing errors
Break detected by reading the RXD32 pin level directly when a
framing error occurs
⎯ Synchronous mode
Serial data communication is synchronized with a clock. In this mode, serial data can be
exchanged with another LSI that has a synchronous communication function.
Data length
Receive error detection
8 bits
Overrun errors
