Debugger in the term of Trap Flag

Describe Debugger in the term of Trap Flag

If the trap flag is set, the after every instruction a type 1 interrupt will be automatically generated. The debugger is made using this interrupt. It allows one instruction to be executed and then return control to us. It has its display code and its code to wait for the key in the INT 1 handler. Therefore after every instruction the values of all registers are shown and the debugger waits for a key.
