Education for ALL: Timing Diagram for STA 526AH - Blogger
WebTiming Diagram for STA 526AH. STA means Store Accumulator -The content of the accumulator is stored in the specified address (526A). The op-code of the STA instruction is said to be 32H. It is fetched from the memory 41FFH (see fig). - OF machine cycle. WebFig: Opcode fetch timing diagram. Operation: During T1 state, microprocessor uses IO/M (bar), S0, S1 signals are used to instruct microprocessor to fetch opcode. Thus when IO/M (bar)=0, S0=S1= 1, it indicates opcode fetch operation. During this operation 8085 transmits 16-bit address and also uses ALE signal for address latching. open source ip management
