1.5 Device Memory Map

Table 1-1 and Figure 1-2 show the device memory map of the MC9S12DT128 after reset. Note that after

reset the EEPROM ($0000 – $07FF) is hidden by the register space ($0000 - $03FF) and the RAM ($0000

- $1FFF). The bottom 1K Bytes of RAM ($0000 - $03FF) are hidden by the register space.
