4.1 MC9S08EL32 Series and MC9S08SL16 Series Memory Map
As shown in Figure 4-1, on-chip memory in the MC9S08EL32 Series and MC9S08SL16 Series consists
of RAM, EEPROM, and 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 0x18FF)
• Nonvolatile registers (0xFFB0 through 0xFFBF)
