So we have the content of ac in the basic computer, hexadecimal a937, and the initial value of u is 1.
00:06
We have to determine the contents of ace, pca, rna, and hexadecimal after the execution of these instructions.
00:12
And they're repeated 11 more times starting from each one of the register reference instructions and the initial value of pc is hexadecimal 021.
00:20
So we have the initial state of the register.
00:23
We have our accumulator or ac at a937, our extension bit at 1, our proton counter is 021, and then our address register is going to be undefined initially and so is our instructions register.
00:44
Now consider the cla, click clear ac instructions.
00:49
After executing we would end up getting ac of 0, e of 1, pc of 021, and then undefined, undefined, and er and ir will depend on the address accessed and then the instructions fetched...
