None
Return from Interrupt. Stack is POPed
and Top-of-Stack (TOS) is loaded in
the PC. Interrupts are enabled by
setting Global Interrupt Enable bit,
GIE (INTCON<7>). This is a two-cycle
instruction.

The W register is loaded with the eight
bit literal ‘k’. The program counter is
loaded from the top of the stack (the
return address). This is a two-cycle
instruction.

The contents of register ‘f’ are rotated
one bit to the left through the Carry
flag. If ‘d’ is ‘ 0 ’, the result is placed in
the W register. If ‘d’ is ‘ 1 ’, the result is
stored back in register ‘f’.
