POP PSW,PC,LR
Specify "PUSH ELR, EPSW" to save the interrupt return address and the PSW status in the stack.
Specify "POP PSW, PC" to return the contents of the stack to PC and PSW.
Specify "PUSH ELR, LR, EPSW" to save the interrupt return address, the subroutine return address,
and the EPSW status in the stack.
Specify "POP PSW, PC, LR" to return the saved data of the interrupt return address to PC, the saved data
of EPSW to PSW, and the saved data of LR to LR.
