Flags affected are always shown in the PSW bit order: SZKAPVC. If a flag is marked by "0" it means it is reset after the instruction. If it is marked by "1" it 8080 had seven byte-registers: A, B, C, D, E, H, and L. A was the 8-bit accumulator for most arithmetical and logical instructions and the other six could8080 instruction encoding: Conventions in instruction source: D = Destination flag not set) 001=Z ('Z'ero flag set) 010=NC ('C'arry flag not set) 011=C The higher number (on the left side of "/") means duration of instruction when action is taken, the lower number (on the right side of "/") means duration of In a. FETCH machine cycle, the processor interprets the data on its data bus as an instruction. During a MEMORY READ or a STACK READ, data on this bus is The 8080 microprocessor program instructions may be one byte, two or three bytes in length. Different byte instructions have to store in successive memory The 8080 instruction set includes con- ditional branching, decimal as well as binary arithmetic, logical, register-to-register,stack control and memory Instructions in an assembly language source program are represented by their assembly language mnemonic. A program written to help in the process of creating The initial specified clock rate or frequency limit was 2 MHz, with common instructions using 4, 5, 7, 10, or 11 cycles. As a result, the processor is able
