What is the significance of the hold and hlda pins?..

Answer / Chandra Prakash Prasad

The HOLD and HLDA (Hold with Acknowledge) pins in the 8085 microprocessor are used to halt the processor's operation when an external device requires it. The HLD pin is asserted by the device, and the HOLD pin disables the clock signal until the device deasserts the HLD pin.
