1.2 Introduction
The MC68H(R)C908JL3E is a member of the low-cost, high-
performance M68HC08 Family of 8-bit microcontroller units (MCUs).
The M68HC08 Family is based on the customer-specified integrated
circuit (CSIC) design strategy. All MCUs in the family use the enhanced
M68HC08 central processor unit (CPU08) and are available with a
variety of modules, memory sizes and types, and package types.
