PIC18F1220/1320
RRNCF Rotate Right f (no carry)
Syntax: [ label ] RRNCF f [,d [,a]]
Operands: 0 ≤ f ≤ 255
d ∈ [0,1]
a ∈ [0,1]
Operation: (f<n>) → dest<n – 1>,
(f<0>) → dest<7>
Status Affected: N, Z
Encoding:
0100 00da ffff ffff
Description: The contents of register ‘f’ are
rotated one bit to the right. If ‘d’ is
‘0’, the result is placed in W. 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’, then the bank will be selected
as per the BSR value (default).

SETF Set f
Syntax: [ label ] SETF f [,a]
Operands: 0 ≤ f ≤ 255
a ∈ [0,1]
Operation: FFh → f
Status Affected: None
Encoding:
0110 100a ffff ffff
Description: The contents of the specified
register are set to FFh. If ‘a’ is ‘0’,
the Access Bank will be selected,
overriding the BSR value. If ‘a’ is
‘1’, then the bank will be selected
as per the BSR value (default).
