Program Memory
The eZ8 CPU supports 64KB of Program Memory address space. The Z8F640x family
devices contain 16KB to 64KB of on-chip Flash memory in the Program Memory address
space. Reading from Program Memory addresses outside the available Flash memory
addresses returns FFH. Writing to these unemployments Program Memory addresses pro-
duces no effect. Table 4 describes the Program Memory Maps for the Z8F640x family
products.
