IV) EEPROM Access
[1] Command for enabling to write the data in the EEPROM (EWEN)
‘
EWEN
’
command makes it possible to write the data in the EEPROM. It is necessary to execute this
command before writing the data in the EEPROM, because it is automatically set at
‘
Power ON
’
to prohibit
writing the data in the EEPROM. In
“
Training mode
”
, it is always possible to write the data in the EEPROM
after executing this command except the case of
‘
Power OFF
’
or executing
‘
EWDS
’
command.
[2] Command for prohibiting to write the data in the EEPROM (EWDS)
‘
EWDS
’
command makes it impossible to write the data in the EEPROM and it is the same setting at
‘
Power ON
’
. This command is available to change the setting to prohibit writing the data in the EEPROM
without
‘
Power OFF
’
.
[3] Command for writing the data in the EEPROM (WRITE-EEP)
It is able to write the data in the nominated EEPROM by executing
‘
WRITE-EEP
’
command. And it is
necessary to execute
‘
EWEN
’
command at first for permitting to write the data in the EEPROM.
[4] Command for reading the data in the EEPROM (READ-EEP)
It is able to read the data held in the nominated EEPROM by executing
‘
READ-EEP
’
command.
