2.1 Introduction
This section describes the organization of the memory on the MC68HC705JJ7/MC68HC705JP7.
2.2 Memory Map
The central processor unit (CPU) can address 8 kilobytes of memory space as shown in

The erasable programmable read-only memory (EPROM) portion of memory holds the program
instructions, fixed data, user-defined vectors, and interrupt service routines.
The random-access memory (RAM) portion of memory holds variable data.
Input/output (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.
The first 32 addresses of the memory space, $0000–$001F, containing the I/O registers section
