what is the clock frequency for 8085?

Correct Answer: RST 45 is called as TRAP

Correct Answer: Yes, it can be used, if an accurate clock frequency is not required also the component cost is low compared to LC or Crystal

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: 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

Correct Answer: RST0, RST1, RST2, RST3, RST4, RST5, RST6, RST7

Correct Answer: TRAP, RST75, RST65, RST55, INTR
