I think the lack of answers may be as your question is hard to understand, what do you mean by head address, can you explain a bit more about your problem ?

[FONT=&quot]How i write the instruction of clock set
[/FONT]

I think you are getting a little confused,
The TWR instruction sets the real time clock and uses 7 data words to do it. The RTC resides in data registers D8013 through to D8019, so to set these values you need to place the new values to want to be set in 7 data words of your choice and use these in the TWR instruction.
The example in the manual uses Datawords D0 through to D6 [TWR D0], so when it is executed it will write D0 to D6 into D8013 to D8019.

I Hope this is clear.

Hi nehpets,
i agree with you but when you write in D0 to D6 [TWR D0] and change the data it could not written in D8013-D8019 and do not change the date time.if you have Example please give me.thanks
