Can RC circuit be used as clock source for 8085?

Correct Answer: Yes so if 8529 gives interrupt then it will be serviced immediately but since INTA pin is left hanging the INSR bit will never be set and so whenever my interrupt occurs depending upon priority it will be serviced also the ISR address for all interrupts will be same ie 0024H Interrupt via trap is nonmaskable, so it will be serviced immediately

Correct Answer: As W and Z alphabets are not widely used similarly as W and Z is internally used they would have been named so

Correct Answer: In case of Move A to B it will move whatever the value of A into BIt mean it will move numeric, alphanumeric and alphabatic value In case of COMPUTE B=A it will assign the value of A into B But in case of compute only numeric value will be compute

Correct Answer: Object Repository means not a collection of objects it's a common repository for all the people (testing, developers) for seeing all the data in single login for example QA wants to see 5 testers works then he goes to each person login and see the data It's very difficult job for this we can use Object Repository

Correct Answer: Micro processor is a program-controlled device, which fetches the instruction from memory, decodes and executes the instructions Most Micro Processor are single-chip devices

Correct Answer: RST 45 is called as TRAP

Correct Answer: 3MHz is the maximum clock frequency for 8085

Correct Answer: There are 12 interrupts in 8085

Correct Answer: Immediate, Direct, Register, Register indirect, Implied addressing modes

Correct Answer: TRAP has the highest priority there are 2 types of interrupts external and internal NMI has highest priority among all external interrupts, TRAP has highest priority among all internal interrupts
