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.
For additional detail, please refer to volume 1 of the HCS08 Reference Manual, (Freescale Semiconductor
document order number HCS08RMv1/D).
The MC9S08AC60 series of microcontrollers has an inter-integrated circuit (IIC) module for
communication with other integrated circuits.
