Chapter 13
Serial Interface

13.1 Overview

The LSI has 4 serial interfaces (SCIF0/SCIF1/SCIF2/SCIF3), which support the following types of communica-
tion.
Table:13.1.2 shows pins used for each SCIF. Each SCIF has two pin groups, Group-A and Group-B.
In this chapter, the suffix of "A" and "B" is omitted to describe functions of SCIF.
Pin group
Clock synchronous
Full duplex UART
Multi master IIC
The combination of pins of Group-A and Group-B must not be used.
For example, in SCIF0 Clock-Synchronous communication, the pin combination of SBO0A
(Group-A), SBI0A (Group-A), and SBT0B (Group-B) is not be allowed.
