Preliminary Technical Data
Enabling Flash Protection by Emulator Commands
Another way to set the flash protection bytes is to use some
reserved emulator commands available only in download mode.
These commands write directly to the SFRs and can be used to
duplicate the operation mentioned in the Enabling Flash
Protection by Code section. Once these flash bytes are written,
the part can exit emulation mode by a reset and the protections
are effective. This method can be used in production and
implemented after downloading the program. The commands
ADE7566/ADE7569
Protection bits can be modified from a 1 to a 0, even after the
last page has been protected. In this way, more protection can
be added but none can be removed.
The protection scheme is intended to protect the end system. Pro-
tection should be disabled while developing and emulating code.
Flash Memory Timing
Typical program and erase times for the flash memory are
shown in Table 97.
used for this operation are an extension of the commands listed
in the Application Note uC004: Understanding the Serial
Download Protocol.

By omitting the protocol defined in the uC004: Understanding
the Serial Download Protocol application note, the sequence to
load protections are similar to the sequence presented in the
Enabling Flash Protection by Code section, except that two
emulator commands are necessary to replace one assembly
command. For example, to write the protection value in
EADRH, the two following commands need to be executed:
? Command I with data = value of protection byte 0x3FFF.
? Command F with data = 0xC7.
Following this protocol, the protection can be written to the
flash using the same sequence as mentioned in the Enabling
Flash Protection by Code section. When the part is reset, the
protection is effective.
Notes on Flash Protection
The flash protection scheme is disabled by default so that none
of the pages of the flash are protected from reading or writing/
erasing.
The last page must be read and write/erase protected for the
protection scheme to work.
To activate the protection settings, the ADE7566/ADE7569
must be reset after configuring the protection.
After configuring protection on the last page and resetting the
part, protections that have been enabled can only be removed by
mass erasing the flash memory. The protection bits are read and
erase protected by enabling read and write/erase protection on the
last page, but the protection bits are never truly write protected.

Note that the core microcontroller operation is idled until the
requested flash memory operation is complete. In practice, this
means that even though the flash operation is typically initiated
with a two-machine-cycle MOV instruction to write to the
Flash Control SFR (ECON, 0xB9), the next instruction is not
executed until the Flash/EE operation is complete. This means
that the core cannot respond to interrupt requests until the
Flash/EE operation is complete, although the core peripheral
functions, such as counters and timers, continue to count as
configured throughout this period.
IN-CIRCUIT PROGRAMMING
Serial Downloading
The ADE7566/ADE7569 facilitate code download via the
standard UART serial port. The parts enter serial download
mode after a reset or a power cycle if the SDEN pin is pulled low
through an external 1 kΩ resistor. When in serial download
mode, the hidden embedded download kernel executes. This
allows the user to download code to the full 16 kB of flash memory
while the device is in-circuit in its target application hardware.
Protection configured in the last page of the ADE7566/ADE7569
affects whether flash memory can be accessed in serial download
mode. Read protected pages cannot be read. Write/erase protected
pages cannot be written or erased. The configuration bits
cannot be programmed in serial download mode.
