Flash Memory
The eZ80F91 Mini Enet Module features 256 KB of on-chip Flash mem-
ory, which can be programmed a single byte at a time, or in bursts of up to
256 bytes. Write operations can be performed using either memory or I/O
instructions. Erasing bytes in Flash memory returns them to a value of
FFh
timed by the Flash controller, leaving the CPU free to execute other oper-
ations in parallel. Upon power-up, the on-chip Flash memory is located in
the address range
in Flash control register
On-chip Flash memory is prioritized over all external Chip Selects, can be
enabled or disabled (power-on enabled), and can be programmed within
any 256 KB address space in the 16 MB address range.
The eZ80F91 Mini Enet Module features the following memory configu-
