Syntax:
Operands:
[

] RLF f,d
0
≤
f
≤
127
d
∈
[0,1]
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’.

Description:
RETURN
Return from Subroutine
Syntax:

Operation:
Status Affected:
Description:
[

] RETURN
None
TOS
→
PC
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.

See description below
C
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 ‘

SUBLW
Subtract W from Literal
Syntax:

Operation:
Status Affected: C, DC, Z
Description:
[

k
≤
255
k - (W)
→ (
W)
The W register is subtracted (2’s
complement method) from the
eight-bit literal ‘k’. The result is
placed in the W register.
SUBWF
Subtract W from f
Syntax:
Operands:
[
label
] SUBWF f,d
0
≤
f
≤
127
d

destination)
Operation:
Status Affected: C, DC, Z
Description:
Subtract (2’s complement method)
W register from register ‘f’. If ‘d’ is
‘
0
’, the result is stored in the W
register. If ‘d’ is ‘
1
’, the result is
stored back in register ‘f’.
