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’.

The power-down Status bit, PD is
cleared. Time-out Status bit, TO is
set. Watchdog Timer and its pres-
caler are cleared.
The processor is put into Sleep mode
with the oscillator stopped.

Subtract W from f
[ label ]
0 f 127
d  [0,1]
(f) - (W) destination)
C, DC, Z
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.
Subtract W from literal
[ label ]
0 k 255
k - (W) W)
C, DC, Z
The W register is subtracted (2’s com-
plement method) from the eight-bit
literal ‘k’. The result is placed in the W
register.

C, DC, Z
Subtract W and the BORROW flag
(CARRY) from register ‘f’ (2’s comple-
ment method). If ‘d’ is ‘0’, the result is
stored in W. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.
