we don't need to increment the PC register here as it is already taken care of in the fetch part of the fetch-decode-execute cycle before it entered the subroutine. Program execution is resumed from where it was, and the program halts as the Halt instruction is executed. The major part of subroutines is that it can be reused.

The microprocessor follows a sequence: Fetch, Decode, and then Execute. Initially, the instructions are stored in the memory in a sequential order. The microprocessor fetches those instructions from the memory, then decodes it and executes those instructions till STOP instruction is reached. Later, it sends the result in binary to the output port.
