5.1 MC68306 ADDRESS SPACE
The full 32-bit address capability of the MC68306 (corresponding to a 4-Gbyte address
space) is decoded internally. A small portion of this address space is devoted to internal
resources such as the serial module, configuration registers, and parallel ports. Table 5-1
is a memory map of the MC68306.
