Problem with K8048

Hi ¡

I´m new in this forum. My name is Javi, (I´m from Spain)

I use one of the demos for try my k8048, the program compile OK, but, when i´m going to write it into the PIC, I have that error:

"    Write error at:0000
     Wrote: 280A
     Read: 3FFF      "

I use the manual of the official page, and I do all like the manual, but I can´t write any program… :confused:

How can I repare it ¿?¿?

( Sorry, but my level of English, is very very horrible…)

Thanks ¡¡¡¡
