The MC68HC11P2 MCU includes 1024 bytes of on-chip RAM, 32kbytes
of ROM/EPROM and 640 bytes of EEPROM. The bootloader ROM
occupies a 512 byte block of the memory map. The CONFIG register is
implemented as a separate EEPROM byte.
Memory locations for on-chip resources are the same for both expanded
and single chip modes. The 128-byte register block originates at $0000
after reset and can be placed at any other 4k boundary ($x000) after
reset by writing an appropriate value to the INIT register. Refer to
3-1, which shows the memory map.
