　　1.1 Overview

　　The MC9S08AW60, MC9S08AW48, MC9S08AW32, and MC9S08AW16 are members of the low-cost,high-performance HCS08 family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced HCS08 core and are available with a variety of modules, memory sizes, memory types, and package types. Refer to Table 1-1 for memory sizes and package types.

　　Table 1-2 summarizes the peripheral availability per package type for the devices available in the MC9S08AW60 Series.

　　1.2 MCU Block Diagrams

　　The block diagram shows the structure of the MC9S08AW60 Series.

　　Figure 1-2. System Clock Distribution Diagram

　　Some of the modules inside the MCU have clock source choices. Figure 1-2 shows a simplified clock connection diagram. The ICG supplies the clock sources:

　　• ICGOUT is an output of the ICG module. It is one of the following:

　　— The external crystal oscillator

　　— An external clock source

　　— The output of the digitally-controlled oscillator (DCO) in the frequency-locked loop sub-module

　　— Control bits inside the ICG determine which source is connected.

　　• FFE is a control signal generated inside the ICG. If the frequency of ICGOUT > 4 × the frequency of ICGERCLK, this signal is a logic 1 and the fixed-frequency clock will be ICGERCLK/2.

　　Otherwise the fixed-frequency clock will be BUSCLK.

　　• ICGLCLK — Development tools can select this internal self-clocked source (~ 8 MHz) to speed up BDC communications in systems where the bus clock is slow.

　　• ICGERCLK — External reference clock can be selected as the real-time interrupt clock source.

　　Can also be used as the ALTCLK input to the ADC module.
