i am using C51 compiler for my project.i downloaded C51 compiler from u'r web.i have a doubt that how to write programs for atmel89052 microcontroller i.e, the codes in writing programs.for eg.in calling tcon or any port how can i use the words either TCON or tcon.
thanks.
u'r web what is that? the microresistor web? what does that have to do with programming?
I can not help you when I do not understand your post.
one thing I can deduct is that you are totally wrong in calling tcon TCON is a SFR, not a function.
