HLT Halt Instruction

The microprocessor halts  the execution  of the  program and enters into  the wait  state  the address  and data bus are placed in the  high  impedance state. An interrupt  or reset  is necessary to exit from the halt  state. The instruction format is


The contents of the  registers and flags are  unaffected  during  the halt  state.
