Created page with "= Action = Write a variables content to the DATA EEPROM. &nb..."

New page

== (**COPIED FROM ENGLISH PAGE**) === Action =

Write a variables content to the DATA EEPROM.

address

| valign="top" width="100%" style="width: 514px; border: 1px solid rgb(0, 0, 0);" |
The address in the EEPROM where the variable must be stored.

 

A new option is that you can provide a label name for the address. See example 2.

</div>
 

This statement is provided for compatibility with BASCOM-8051.

 

You can also use :

Dim V as Eram Byte  'store in EEPROM

Dim B As Byte  'normal variable

B = 10

V = B    'store variable in EEPROM

 

When you use the assignment version, the data types must be the same!

 

According to a data sheet from ATMEL, the first location in the EEPROM with address 0, can be overwritten during a reset. It is advised not to use this location.

 

For security, register R23 is set to a magic value before the data is written to the EEPROM.

All interrupts are disabled while the EEPROM data is written. Interrupts are enabled automatic when the data is written.

 

It is advised to use the Brownout circuit that is available on most AVR processors. This will prevent that data is written to the EEPROM when the voltage drops under the specified level.

 

When data is written to the EEPROM, all interrupts are disabled, and after the EEPROM has been written, the interrupts are re-enabled.

 

In the XMEGA, you need to set the mode to mapped : [[CONFIG EEPROM|CONFIG EEPROM]] = MAPPED.
