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.

Time-out Status bit (TO) is set. The
Power-down Status bit (PD) is
cleared.
RBWUF is unaffected.
The WDT and its prescaler are
cleared.
The processor is put into Sleep
mode with the oscillator stopped.

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’.

C, DC, Z
Subtract (2’s complement method)
the 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’.

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
‘1’, the result is placed back in
register ‘f’.

None
The upper and lower nibbles of
register ‘f’ are exchanged. If ‘d’ is
‘0’, the result is placed in W
register. If ‘d’ is ‘1’, the result is
placed in register ‘f’.
