Program Memory
The eZ8 CPU supports 64 KB of program memory address space. The Z8 Encore! XP
F64xx Series contains 16 KB to 64 KB of on-chip Flash in the program memory address
space, depending upon the device. Reading from program memory addresses outside the
available Flash memory addresses returns FFH. Writing to these unimplemented program
memory addresses produces no effect. Table 5 describes the program memory maps for
the Z8 Encore! XP F64xx Series products.
