3.2 RAM
All members of the M68HC11 K series have 768 bytes of static RAM. The RAM can be mapped to any
4-Kbyte boundary. Upon reset, the RAM is mapped at $0080–$037F. The registers are also mapped to
this 4-Kbyte boundary. In previous versions of the M68HC11 devices the register block being mapped
to the same boundary would cause the portion of RAM overlapped by the register block to be lost. How-
ever, a new RAM remapping feature has been added which automatically allows all of the RAM to be
accessible even if the register block overlaps the RAM. Because the registers are located in the same
