Microprocessor
Assertion (A): Each memory chip has its own address latch. Reason (R): ALE signal comes out of microprocessor 8085 and goes to memory chip.
A is wrong R is correct
Both A and R are correct but R is not correct explanation of A
A is correct R is wrong
Both A and R are correct and R is correct explanation of A
While the microprocessor is executing a program an interface circuit takes over control of address, data, control buses when not in use by microprocessor
The DMA control waiting for the microprocessor to finish execution of the program and then takes over the buses
Data transfer takes place between the I/O device and memory during every alternate clock cycle
DMA controller taking over the address, data and control buses while a block of data is transferred between memory and I/O device
