Section 10 Serial Communication Interface
10.1 Overview
This LSI is provided with three serial communication interface (SCI) channels. The functions of
the three SCI channels are summarized in table 10.1.
Table 10.1 Overview of SCI Functions
SCI Name Functions Features
SCI1 Synchronous serial transfer functions
• Choice of transfer data length (8 or 16
bits)
• Continuous clock output function
• Choice of 8 internal clocks (φ/1024 to φ/4,
φ
W
/4) or external clock
• Open-drain output option
• Interrupt generated on completion of
transfer
SCI31,
SCI32
Synchronous serial transfer functions
