Chapter 12 Serial Interface 3

12-1 Overview

This LSI contains a serial interface 3 can be used for both communication types of clock synchronous and simple IIC (single master).

12-1-1 Functions

Table 12-1-1 shows the functions of serial interface 3.

Table 12-1-1 Serial Interface 3 Functions List

Communication type			Clcok synchronous	IIC (single master)
Interrupt			SC3IRQ	SC3IRQ
Pin			SBO3, SBI3, SBT3	SDA, SCL
3 channels type				-
2 channels type			(SBO3, SBT3)
Start condition
Transfer bit count			1 to 8 bit	1 to 8 bit
First transfer bit
Input edge / Output edge				-
ACK bit			-
ACK bit level			-
Continuous operation (with ATC1)				-
			fosc/2	fosc/2
			fosc/4	fosc/4
			fosc/16	fosc/16
Clock source			fosc/32	fosc/32
			fs/2	fs/2
			fs/4	fs/4
			timer 5 output	timer 5 output
			external clock	external clock
Maximum transfer rate			2.5 MHz	400 kHz
fosc : machine clock (high speed		oscillation)
fs : system clock [	Chapter 2		2-5. Clock Switching	]

At IIC communication, the transfer clock is the clock source divided by 3.
