Which of the following is true while executing data transfer instructi...
Answer:
The correct option is (C) - both operands can be direct/indirect register operands.
When executing data transfer instructions, there are several important considerations to keep in mind.
1. Program Counter Access:
- The program counter (PC) is a register that keeps track of the memory address of the next instruction to be executed.
- While executing data transfer instructions, the program counter is accessible and can be modified if necessary. Therefore, option (a) - "program counter is not accessible" is incorrect.
2. Restricted Bit-Transfer Operations:
- Bit-transfer operations involve transferring bits from one location to another.
- While executing data transfer instructions, there are no restrictions on bit-transfer operations. Therefore, option (b) - "restricted bit-transfer operations are allowed" is incorrect.
3. Operand Types:
- Data transfer instructions involve transferring data from one location to another.
- These instructions typically involve two operands - the source operand and the destination operand.
- Both operands can be direct register operands, meaning they directly reference a register in the CPU.
- Additionally, both operands can be indirect register operands, meaning they reference a memory location that contains the address of the actual data.
- Therefore, option (c) - "both operands can be direct/indirect register operands" is correct.
- This flexibility allows for efficient data transfer between registers and memory locations.
In conclusion, while executing data transfer instructions, the program counter is accessible, there are no restrictions on bit-transfer operations, and both operands can be direct or indirect register operands. Therefore, option (c) is the correct choice.
The correct option is (C) - both operands can be direct/indirect register operands.
