QUESTION 3 The memory architecture for a Cortex-M4 microprocessor is descending, full. The general-purpose register R13 in a Cortex-M4 microprocessor contains Ox3FFB F67C. The processor then executes the Assembly language instruction: POP {RO, R11, R12}; What is the contents of R13 at the end of the execution? R13 = Which register (RO, R11, R12) was the last to be loaded with contents from the stack? QUESTION 4 The memory architecture for a Cortex-M4 microprocessor is descending, full. The general-purpose register R13 in a Cortex-M4 microprocessor contains 0x346F9C70. The processor then executes the Assembly language instruction: POP {R3, R5, R2}; What is the contents of R13 at the end of the execution? R13 = Which register (R3, R5, R2) was the first to be loaded with contents from the stack
