how isp works s52
i've just buy a new at89s53 micro, but somehow i can't erase or write my program into it via isp programmer, all i can do is read it, and it happened on my at89s8252 too.
my assumption is that the isp fuse is going to disabled (even on datasheet they said that default condition is enabled). my question,
is it possible to disable the fuse on isp programming mode, coz i never use the parallel method and my micro fuse is going to disabled, and i just want to know how?
i want to program the micro using isp mode, how to avoid the fuse change into disable condition?
is there another way to re-enable the fuse beside parallel method?
a lot of thanx b4
