MC68HC08LJ12
The MC68HC08LJ12 is the ROM part equivalent to the MC68HC908LJ12.
MCU Block Diagram
Figure 4
shows the block diagram of the MC68HC08LJ12.
Memory Map
The MC68HC08LJ128 has 12,288 bytes of user ROM from $C000 to $EFFF,
and 48 bytes of user ROM vectors from $FFD0 to $FFFF. On the
MC68HC908LJ12 these memory locations are FLASH memory.
Figure 5
shows the memory map of the MC68HC08LJ12.
Reserved Registers
The two registers at $FE08 and $FE09 are reserved locations on the
MC68HC08LJ12.
On the MC68HC908LJ12, these two locations are the FLASH control register
and the FLASH block protect register respectively.
Monitor ROM
The monitor program (monitor ROM: $FE10–$FFCF and $FC00–$FDFF) on
the MC68HC08LJ12 is for device testing only.
