Differentiations between the HOLD and HLT states

Question

Write down the differentiations between the HOLD and HLT states?

Answer 1

• The Hold is a hardware input while HLT is a software command.
• When the HLT state is carried out the processor basically stops and the buses are driven to tri state. No form of acknowledgement signal is given out through the processor.
• In case of HOLD the processor goes in hold state however the buses are not driven to tri state.
• When the processor goes in the HOLD state it gives out an HLDA signal. This signal can be made to employ through other devices.
