Serial Interface
13-2
13.1 Overview
This microcontroller has three types of internal serial interfaces. One is a general-purpose serial interface for which
clock synchronous mode, UART mode, or I2C mode can be specified; this interface supports one channel. The
second interface is a clock synchronous serial interface that supports two channels. The third interface is UART
serial interface that supports one channel.
