1/2 of it for the high and low portions of the pulse = 10 ms 10 ms / 1.085 us = 9216 and 65536 - 9216 = 56320 in decimal, and in hex it is DCOOH. The assembly languages differ, but the instructions supported by both translate to the same machine code and an 8080 program should be able to run on a Z80. Atfirst we assume that , CWR address of 8255 is 0B and SOC pin of 0808 is connected to 0th pin of PORT B. MVI A,89H. In our subject, 1 True and 0 False, so if you make M 7.5 to be 1, surely RST 7.5 will be masked, unmasked otherwise. All the instructions in this microprocessor are encoded in a single byte. Instead of mugging up, where 1 means what, and 0 means what else, get one fact clear. Then when you connect an oscilloscope to this pin, you can see the waveform to be a square wave. Use MathJax to format equations. Please use ide.geeksforgeeks.org, if count not zero loop DELAY. Examples When you are in any number system, not only binary, there you write the least significant bit at the rightmost place and most significant bit at the leftmost place.
