Hi. I am currently working for the first time in 6 years on a Texas Instrument OTP. My question is this. I have a measurement chip, namely AD7755 series, clocking out pulses directly to P0 on my TI chip. The measurement chip is basically clocking out pulses generated from its AC input signal. Now, I need to have a prescaler for multiplication and division for some reason. I have basically setup the software to generate an interrupt everytime it receives a pulse on that port. Your help would be greatly appreciated for this newbie.

Thanks in advance.
