13.1
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.
For additional detail, please refer to volume 1 of the HCS08 Reference Manual, (Freescale Semiconductor
document order number HCS08RMv1/D).
13.1.1
The IIC includes these distinctive features:
13.1.2
The IIC functions the same in normal and monitor modes. A brief description of the IIC in the various
MCU modes is given here.

Run mode — This is the basic mode of operation. To conserve power in this mode, disable the
module.
Wait mode — The module will continue to operate while the MCU is in wait mode and can provide
a wake-up interrupt.
Stop mode — The IIC is inactive in stop3 mode for reduced power consumption. The STOP
instruction does not affect IIC register states. Stop1 and stop2 will reset the register contents.
