1.5 Device Memory Map
MC9S12DJ64 Device User Guide — V01.17
Table 1-1 and Figure 1-2 show the device memory map of the MC9S12DJ64 after reset. The 1K
EEPROM is mapped twice in a 2K address space. Note that after reset the bottom 1k of the EEPROM
($0000 - $03FF) are hidden by the register space, and the 1K $0400 - $07FF is hidden by the RAM.
