Microprocessor Assertion(A): Ready signal of microprocessor is used to detect whether a peripheral is ready for the data transfer or not. Reason(R): In the microprocessor during data transfer operations, the wait states are added by forcing the ready signal low. Both A & R are true and R is the correct explanation of A. A is true but R is false. A is false but R is true. Both A & R are true but R is not the correct explanation of A . Both A & R are true and R is the correct explanation of A.

Microprocessor HLDA signal in 8085 performs the following operation: Hold the data in the accumulator until the microprocessor is turned OFF. Indicates that another master is requesting the use of the address and data buses. Indicates that the CPU has not received the HOLD request. Indicates that the CPU has received the HOLD request and that it will relinquish the bus in the next clock cycle. Hold the data in the accumulator until the microprocessor is turned OFF.

Microprocessor The reason for the presence of ALE pin in 8085, but not in 6800 is that 8085 has multiplexed bus, whereas 6800 does not have 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has 5 interrupts lines, whereas 6800 has only two None 8085 has multiplexed bus, whereas 6800 does not have 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has 5 interrupts lines, whereas 6800 has only two None ANSWER DOWNLOAD EXAMIANS APP
