Description
This instruction returns from a subroutine by restoring the program counter (PC) from the stack.
Program execution continues from the address restored to the program counter. The PC contents at
the time of execution of this instruction are lost.
Operand Format and Number of States Required for Execution
Notes
The stack structure and number of states required for execution differ between normal mode and
advanced mode. In normal mode, only the lower 16 bits of the program counter are restored.
