4.1 MC9S08GBxxA/GTxxA Memory Map
As shown in Figure 4-1, on-chip memory in the MC9S08GBxxA/GTxxA series of MCUs 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 0x007F)
• High-page registers (0x1800 through 0x182B)
• Nonvolatile registers (0xFFB0 through 0xFFBF)
