Inter-Integrated Circuit (S08IICV2)
11.1
The inter-integrated circuit (IIC) provides a method of communication between a number of devices. The
interface is designed to operate up to 100 kbps with maximum bus loading and timing. The device is
capable of operating at higher baud rates, up to a maximum of clock/20, with reduced bus loading. The
maximum communication length and the number of devices that can be connected are limited by a
maximum bus capacitance of 400 pF.
All MC9S08DZ128 Series MCUs in the 100-pin package have two IICs; devices in the 64-pin and 48-pin
packages have one IIC.
11.1.1
The IIC1 module pins, SDA1 and SCL1 can be repositioned under software control using IIC1PS in
SOPT1 as shown in
with the IIC1 operation.

Introduction
IIC1 Configuration Information
MC9S08DZ128 Series devices operate at a higher voltage range (2.7 V to
5.5 V) and do not include stop1 mode. Please ignore references to stop1.
