Return from Subroutine
[ label ]
None
TOS
None
Return from subroutine. The stack
is POPed and the top of the stack
(TOS) is loaded into the program
counter. This is a two-cycle
instruction.
Return from Interrupt
[ label ]
None
TOS
1
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 pro-
gram counter is loaded from the
top of the stack (the return
address). This is a two-cycle
instruction.

Rotate Left f through Carry
[ label ]

d
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’.
Rotate Right f through Carry
[ label ]
0
d
See description below
C
00
The contents of register ‘f’ are
rotated one bit to the right
through the Carry Flag. If ‘d’ is
‘0’, the result is placed in the W
register. If ‘d’ is ‘1’ the result is
placed back in register ‘f’.
