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