Configuration of Passwords
The sequence in figure 14 will change (program) the
write, read and configuration passwords. The program-
ming of passwords is done twice prior to the nonvolatile
write cycle in order to verify that the new password is
consistent. After the eight bytes are entered in the sec-
ond pass, a comparison takes place. A mismatch will
cause the part to reset and enter into the standby mode
and a “no ACK” will be issued.
There is no way to read the Read/Write/Configuration
passwords.
Program Configuration Registers
This mode allows programming of the five configuration/
control registers using the configuration password. The
retry counter must be programmed with a value less than
the retry register. If it is programmed with a value larger
than the retry register there will be a wrap around.
Read Configuration Registers
This mode allows reading of the 5 configuration/control
registers with the configuration password. It may be use-
ful for monitoring purposes.
