Responding to: ???'s previous message
Dear Oleg,
I already build the parallel programming and do programming sequent:

1st sequent:
* Power up
* Delay aprox. 1s
* Chip erase
* Programming fuse
* Read fuse bit
* Delay aprox. 1s
* Power down

2nd sequent:
* Power up
* Delay aprox. 1s
* Chip erase 5 times
* Programming fuse 10 times
* Read fuse bit
* Delay aprox. 1s
* Power down

In the 1st sequent the isp fuse bit can not enabled althought I writed enable for this fuse, I do not know why?
In the 2nd sequent the isp fuse bit can enabled.
Thank you Oleg and everyone to spend your time for reply my problem.
best regard
