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. It is also provided with a multiprocessor communication
function that enables serial data to be transferred among processors.
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). A multiprocessor communication function is also provided, enabling serial data
communication among processors.
There is a choice of 16 data transfer formats.
Data length
7, 8, 5 bits
Stop bit length
1 or 2 bits
Parity
Even, odd, or none
Multiprocessor bit
1 or 0
Receive error detection
Parity, overrun, and framing errors
Break detection
Break detected by reading the RXD
32
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
8 bits
Receive error detection
Overrun errors
