**Instruction Analysis and Addressing Modes**Suppose we have the instruction `LDA 900` and register `R1` contains `0x100`.**Given Memory:**- **Memory** - Address: `0x800`, Value: `900` - Address: `0x900`, Value: `800` - Address: `0xA00`, Value: `500` - Address: `0xB00`, Value: `600` - Address: `0xC00`, Value: `800`**Objective:**Determine what would be loaded into the Accumulator (AC) with the following addressing modes:1. **Immediate Addressing Mode:** - The operand is directly specified within the instruction. - *Answer to be filled in: "Immediate: [your answer]"*2. **Direct Addressing Mode:** - The operand is found at the address specified in the instruction. - *Answer to be filled in: "Direct: [your answer]"*3. **Indirect Addressing Mode:** - The address of the operand is found at the address specified in the instruction. - *Answer to be filled in: "Indirect: [your answer]"*4. **Indexed Addressing Mode:** - The effective address of the operand is computed by adding the content of an index register (e.g., `R1`) to the address part of the instruction. - *Answer to be filled in: "Indexed: [your answer]"* The correct values to fill in the answers will depend on understanding the specified addressing modes and referring to the given memory addresses and their contents.
