This section describes the organization of the memory on the
MC68HC05JJ6/MC68HC05JP6.
The CPU can address eight Kbytes of memory space as shown in
Figure
fixed data, user-defined vectors, and interrupt service routines. The
RAM portion of memory holds variable data. I/O registers are memory
mapped so that the CPU can access their locations in the same way that
it accesses all other memory locations.
