Overview

The serial communication interface 2 (SCI2) that has a 32-byte data buffer carries out clocked
synchronous serial transmission of 32 bytes by a single operation.
24.1.1

Features

SCI2 features are listed below.
• 32 bytes data transfer can be automatically carried out
• Choice of 7 internal clocks (φ/256, φ/64, φ/32, φ/16, φ/8, φ/4, and φ/2) and an external clock
as serial clock source
• Interrupt occurs when transmission has been completed or an error has occurred
• Data transfer at intervals of 1 byte can be set
Data transfer can be carried out at intervals of 1 byte. The interval can be selected from a
multiple of internal clock cycle by 56, 24, or 8 times
• Start of data transfer can be controlled by input of chip select
• Strobe pulse is output for each 1-byte transfer
