Return from Interrupt
[ label ]
None
TOS → PC,
1 → GIE
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.

Return with literal in W
[ label ]
0 ≤ k ≤ 255
k → (W);
TOS → PC
None
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.

See description below
C
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’.
