Without information about the specific architecture and instruction set being used, it is difficult to provide a definitive answer. However, in general, the JMP instruction is typically used to change the flow of execution to a different memory location or address.
In Example 4.5, R3 contains the value x369C. Depending on the specific instruction set being used, this could represent a memory address that the JMP instruction would jump to. For example, if the instruction set uses a direct addressing mode, the JMP instruction might load the program counter with the value in R3, causing the processor to begin executing instructions at memory address x369C.
Alternatively, if the instruction set uses a relative addressing mode, the JMP instruction might add the value in R3 to the current program counter value to determine the new address to jump to. For example, if the current program counter is x2000 and R3 contains x369C, the JMP instruction might cause the program counter to be set to x569C.
Ultimately, the exact behavior of the JMP instruction will depend on the specific architecture and instruction set being used.
