Returns from EI level exception (Return from Trap or Interrupt)

[Syntax]

[Function]

Returns execution from an EI level exception. The return PC and PSW are loaded from the EIPC and EIPSW registers and set in the PC and PSW, and control is passed.

If EP = 0, it means that interrupt (EIINTn) processing has finished, so the corresponding bit of the ISPR register is cleared.
