4.1 MC9S08AC16 Series Memory Map
Figure 4-1 shows the memory maps for the MC9S08AC16 Series MCUs. On-chip memory in the
MC9S08AC16 Series of MCU consists of RAM, FLASH program memory for nonvolatile data storage,
plus I/O and control/status registers. The registers are divided into three groups:
• Direct-page registers (0x0000 through 0x006F)
• High-page registers (0x1800 through 0x185F)
• Nonvolatile registers (0xFFB0 through 0xFFBF)
