Memory
4.1 Introduction
This chapter describes the on-chip memory in the MC9S08LG32 series of MCUs. It details the memory
map, vector and bit assignments, registers and control bits, and other RAM and flash features.
4.2 MC9S08LG32 Series Memory Map
As shown in Figure 4-1 , on-chip memory in the MC9S08LG32 series of MCUs consists of RAM, flash
memory for nonvolatile data storage, and I/O and control/status registers. The registers are divided into
four groups:
• Direct-page registers (0x0000 through 0x005F)
• LCD data registers (0x0820 through 0x085C)
• High-page registers (0x1800 through 0x187A)
• Nonvolatile registers (0xFFB0 through 0xFFBF)
