Instruction Description
ADDWF
ADD W to f
Syntax:
ADDWF f,d
Encoding:
Words:
1
Cycles:
1
Operation:
(W + f)
→ d
Status bits:
C, DC, Z
Description:
Add the contents of the W register to
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”.
ANDLW
AND Literal and W
Syntax:
ANDLW k
Encoding:
Words:
1
Cycles:
1
Operation:
(W .AND. k)
→ W
Status bits:
Z
Description:
The contents of W register are AND’ed
with the eight bit literal “k”. The result is
placed in the W register.
ANDWF
AND W with f
Syntax:
ANDWF f,d
Encoding:
Words:
1
Cycles:
1
Operation:
(W .AND. f)
→ d
Status bits:
Z
Description:
AND the W register with 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”.
BCF
Bit Clear f
Syntax:
BCF f,b
Encoding:
Words:
1
Cycles:
1
Operation:
0
→ f(b)
Status bits:
None
Description:
Bit “b” in register “f” is reset to 0.

BSF
Bit Set f
Syntax:
BSF f,b
Encoding:
Words:
1
Cycles:
1
Operation:
1
→ f(b)
Status bits:
None
Description:
Bit “b” in register “f” is set to 1.
BTFSC
Bit Test, skip if Clear
Syntax:
BTFSC f,b
Encoding:
Words:
1
Cycles:
1(2)
Operation:
skip if f(b) = 0
Status bits:
None
Description:
If bit “b” in register “f” is “0” then the
next instruction is skipped.
If bit “b” is “0”, the next instruction,
fetched during the current instruction
execution, is discarded and a NOP is
executed instead making this a 2-cycle
instruction.
BTFSS
Bit Test, skip if Set
Syntax:
BTFSS f,b
Encoding:
Words:
1
Cycles:
1 (2)
Operation:
skip if f(b) = 1
Status bits:
None
Description:
If bit “b” in register “f” is “1” then the
next instruction is skipped.
If bit "b" is "1", the next instruction,
fetched during the current instruction
execution, is discarded and a NOP is
executed instead making this a 2-cycle
instruction.
