Contents of the accumulator when the instruction IN PORTO is executed:
When the instruction "IN PORTO" is executed, the contents of the accumulator depend on the value received from the input port connected to the data line D, assuming the switch S- is at logic 1 and all other switches are at logic 0.
1. Understanding the instruction:
- The instruction "IN PORTO" is used to input data from a specified port into the accumulator.
- The port specified here is PORTO, which is connected to the data line D.
- The data received from the port will be stored in the accumulator.
2. Switch configuration:
- In the given scenario, the switch S- connected to the input PORTO is at logic 1, while all other switches are at logic 0.
- This means that a logic 1 signal is being applied to the data line D.
3. Effect on the accumulator:
- When a logic 1 signal is applied to the data line D, the input port PORTO will transfer this value to the accumulator.
- The value received from the input port is 1, as the switch S- is at logic 1.
- Therefore, the accumulator will hold the value 1 after the execution of the "IN PORTO" instruction.
4. Execution of subsequent instructions:
- After the "IN PORTO" instruction, the next instruction is "MOV B, A" which moves the contents of the accumulator to register B.
- So, the value 1 stored in the accumulator will be transferred to register B.
- The subsequent instruction "OUT PORTI" is not relevant to the contents of the accumulator and will not affect its value.
- Finally, the "HLT" (Halt) instruction will stop the execution of the program.
Conclusion:
When the instruction "IN PORTO" is executed with the given switch configuration, the contents of the accumulator will be 1.
