The eZ80F92 features 64 KB (65,536 bytes) of non-volatile Flash memory with Read/
Write/Erase capability. The main Flash memory array is arranged in 64 pages with eight
rows per page and 128 bytes per row. In addition to the main Flash memory there are two
separately addressable rows which comprise a 256 byte Information Page.
The 64 KB of main storage can be protected in four 16 KB blocks. Protecting a 16 KB
block prevents Write or Erase operations.
arrangement.
Flash can be programmed a single byte at a time or in bursts of up to 128 bytes (full row).
Write operations may be accomplished using either memory or I/O instructions. Reading
Flash memory can be accomplished through internal memory access or through the ZDI
and OCI interfaces. The Flash memory controller contains a frequency divider, Flash
register interface, address generator, and the Flash control state machine.
