I'm trying to program a 89C52 from Atmel using the "Programmable Clock-Out" feature. I read the procedure needed on the 89C52 datasheet.

Whenever I try to configure T2CON or T2MOD or when I try to star TR2 by using the instruction: SETB TR2 using Proview32 I get a message saying that it can't recognize those registers.

I tried to configure my whole program to a 89C52 but unfortunately, this microcontroller does not appear. Could that be the source of the problem?

All I want to do is to generate a 33.3 kHz square pulse. If I do this by using timer interrupts, then I get pulses that ARE NOT 1/33.3 s wide.

thanks in advance!
