Memory Map and Register Definition
4.1 MC9S08QG8/4 Memory Map
As shown in Figure 4-1, on-chip memory in the MC9S08QG8/4 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 these groups:
• Direct-page registers (0x0000 through 0x005F)
• High-page registers (0x1800 through 0x184F)
• Nonvolatile registers (0xFFB0 through 0xFFBF)
