Memory Allocation
The EEPROM memory consists of three areas:
A = factory settings; B = user settings; C = stored numbers
A) factory settings
B) user settings
C) stored numbers
programmed in factory
Set-up programming
User-code programming
"reset to factory settings"
…write/read by AS2525
EEPROM
Figure 6: Memory allocation for external EEPROM
The AS2525 is writing and reading to and from area B and C during normal operation and user-code programming.
Area A is protected during normal operation and contains a back-up copy of the factory settings. This back-up copy
can be loaded into area B by the user with the user-code programming procedure "reset to factory settings". The
only way to change the factory settings in area A is by set-up programming using password. After changing area A
by set-up programming, the AS2525 automatically performs a "reset to factory settings" to load this changes also
into area B.
