Inter-Integrated Circuit (S08IICV2)
11.1 Introduction
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 MC9S08DN60 Series MCUs feature the IIC, as shown in the following block diagram.
NOTE
Drive strength must be disabled (DSE=0) for the IIC pins when using the
IIC module for correct operation.
