4.1 MC9S08SG32 Series Memory Map
As shown in Figure 4-1, on-chip memory in the MC9S08SG32 Series series of MCUs consists of RAM,
FLASH program memory for nonvolatile data storage, and I/O and control/status registers. The registers
are divided into three groups:
• Direct-page registers (0x0000 through 0x007F)
• High-page registers (0x1800 through 0x185F)
• Nonvolatile registers (0xFFB0 through 0xFFBF)
