1048 / 1348 page ![]() Chapter 25 2 Kbyte EEPROM Module (S12XEETX2KV1) MC9S12XDP512 Data Sheet, Rev. 2.21 1050 Freescale Semiconductor The EADDRHI and EADDRLO registers are the EEPROM address registers. All EABHI and EABLO bits read 0 and are not writable in normal modes. All EABHI and EABLO bits are readable and writable in special modes. The MCU address bit AB0 is not stored in the EADDR registers since the EEPROM block is not byte addressable. 25.3.2.9 EEPROM Data Registers (EDATA) The EDATAHI and EDATALO registers are the EEPROM data registers. All EDHI and EDLO bits read 0 and are not writable in normal modes. 76543210 R 000000 EABHI W Reset 00000000 = Unimplemented or Reserved Figure 25-13. EEPROM Address High Register (EADDRHI) 76543210 R EABLO W Reset 00000000 = Unimplemented or Reserved Figure 25-14. EEPROM Address Low Register (EADDRLO) 76543210 R EDHI W Reset 00000000 = Unimplemented or Reserved Figure 25-15. EEPROM Data High Register (EDATAHI) 76543210 R EDLO W Reset 00000000 = Unimplemented or Reserved Figure 25-16. EEPROM Data Low Register (EDATALO) |
