In a typical service routine, to go back to the previous code we do RTI. Suppose we replace RTI by a sequence of two instructions: POPpc POPpsw The POPpc instruction will pop the PC value from the control stack (assume that PC, PSW values are on the stack in the right order) and put it into the PC register. The POPpsw instruction will pop the PSW value from the control stack and put it in the PSW register. Assume that all logical addresses are the same as the physical addresses. Will this scheme work?
