I'm going to keep things fairly simple. If I wanted to start the count at 0000 on a 4-bit Synchronous counter, and the counter was correctly set to count up based off the data sheet parameters, would I just ground all 4 inputs to represent lows (0000)?
Same thing if I wanted to count down. If I wanted to start at 15 (1111), would I just set all 4 inputs high (1111), and set the counter to count down?
I'm pretty sure I don't want to use the LOAD function since that just puts the # at the inputs directly at the output without counting.
I'm asking this because I just finished designing and building a 4-bit Counting Digital-to-Analog Converter for a lab. It works fine in Pspice with a beautiful "step cycle" graph. But in Pspice, you hit a "Digital Setup" box and must label the inputs - all 0, all 1, or all X (unknown). It's been 2 years since I've actually done something like this in lab - so I want to make sure I'm doing it right physically. Thanks.
