Description
This instruction returns from an exception-handling routine by restoring the EXR, condition-code
register (CCR) and program counter (PC) from the stack. Program execution continues from the
address restored to the program counter. The CCR and PC contents at the time of execution of this
instruction are lost. If the extended control regiser (EXR) is valid, it is also restored (and the
existing EXR contents are lost).
Operand Format and Number of States Required for Execution
Note: * Six states when EXR is valid.
