Description:
Rotate Left f (no carry)
[ label ] RLNCF f [ ,d [,a] ]
0 ≤ f ≤ 255
d ∈ [0,1]
a ∈ [0,1]
(f<n>) → dest<n+1>,
(f<7>) → dest<0>
N,Z
0100 01da ffff ffff
The contents of register ’f’ are
rotated one bit to the left. If ’d’ is 0
the result is placed in WREG. If ’d’
is 1, the result is stored back in reg-
ister 'f' (default). If ’a’ is 0, the
Access Bank will be selected, over-
riding the BSR value. If ’a’ is 1, the
Bank will be selected as per the
BSR value.

Operation:
Status Affected:
Encoding:
Description:
Rotate Right f through Carry
[ label ] RRCF f [ ,d [,a] ]
0 ≤ f ≤ 255
d ∈ [0,1]
a ∈ [0,1]
(f<n>) → dest<n-1>,
(f<0>) → C,

C,N,Z
0011 00da ffff ffff
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 WREG. If 'd' is 1, the
result is placed back in register 'f'
(default). If ’a’ is 0, the Access
Bank will be selected, overriding
the BSR value. If ’a’ is 1, the Bank
will be selected as per the BSR
value.
