Description:
complement method) from the
eight-bit literal ‘k’. The result is
placed in the W register.
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’.

Affected:
C, DC, Z
Operation:
See description below
C
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’.
Status Affected:
Description:
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’.
SWAPF
Swap Nibbles in f
C
Register f
Syntax:
[ label ] SWAPF f,d
Operands:
0 f 127

None
Status Affected: None
Operands:
Operation:
Description: The upper and lower nibbles of
00h WDT,
0 WDT prescaler,
1 TO,
register ‘f’ are exchanged. If ‘d’ is
0, the result is placed in the W
register. If ‘d’ is 1, the result is
placed in register ‘f’.
0 PD
Status Affected:
Description:
TO, PD
The power-down Status bit, PD is
cleared. Time-out Status bit, TO
is set. Watchdog Timer and its
prescaler are cleared.
The processor is put into Sleep
mode with the oscillator stopped.
