Figure 66: Flash Memory Organization
The flash memory can be protected from read or write/erase
access. The protection is implemented in part of the last page of
the flash memory, Page 31. Four of the bytes from this page are
used to set up write/erase protection for each of the pages.
Another byte is used for configuring read protection of the flash
memory. The read protection is selected for groups of four
pages. Finally, there is a byte used to store the key required for
modifying the protection scheme. If any code protection is
required, the last page of flash memory must be write/erase
protected at a minimum. The implication of write/erase
protecting the last page is that the content of the 506 bytes in
this page that are available to the user must not change.
Thus it is recommended that if code protection is enabled, this
last page should be used for program memory only if the
firmware does not need to be updated in the field. If the
firmware must be protected and can be updated at a future date,
the last page should be used only for constants used by the
program code that will not need to be read during emulation or
debug.
Therefore, Pages 0 through 30 are for general program and data
memory use. It is recommended that Page 31 is used for
constants or code that will not need to be updated. Note that the
last 6 bytes of Page 31 are reserved for protecting the flash
memory.
USING THE FLASH MEMORY
The 16 kbytes of Flash memory are configured as 32 pages, each
of 512 bytes. As with the other ADE7169F16 peripherals, the
interface to this memory space is via a group of registers
mapped in the SFR space – see . A data register, EDATA, holds
the byte of data to be accessed. The byte of flash memory is
addressed via the EADRH and EADRL registers. The Flash

Finally, ECON is an 8-bit control register that can be written to
with one of seven Flash memory access commands to trigger
various read, write, erase, and verify functions. Figure 67
demonstrates the steps required for access to the flash memory.

ECON—Flash/EE Memory Control SFR
Programming Flash memory is done through the Flash
memory control Flash Control SFR (ECON, 0xB9). This SFR
allows the user to read, write, erase, or verify the 16 kbytes of
Flash memory. As a method of security, a key must be written
to the FLSHKY register to initiate any user access to the flash
