What is the maximum clock frequency of 8085 microprocessor?
3 MHz
What is the frequency of a clock?
Its reciprocal, fc = 1/Tc, is the clock frequency. All else being the same, increasing the clock frequency increases the work that a digital system can accomplish per unit time. Frequency is measured in units of Hertz (Hz), or cycles per second: 1 megahertz (MHz) = 106 Hz, and 1 gigahertz (GHz) = 109 Hz.

How clock signal is generated?
A clock signal is produced by a clock generator. Although more complex arrangements are used, the most common clock signal is in the form of a square wave with a 50% duty cycle, usually with a fixed, constant frequency.
Which signals are used in DMA technique?
Two control signals are used to request and acknowledge a direct memory access (DMA) transfer in the microprocessor-based system.
- The HOLD signal as an input(to the processor) is used to request a DMA action.
- The HLDA signal as an output that acknowledges the DMA action.
What is Hlda hold?
HOLD – It indicates that another device is requesting the use of the address and data bus. After the removal of the HOLD signal the processor regains the bus. HLDA – It is a signal which indicates that the hold request has been received after the removal of a HOLD request, the HLDA goes low.
