PIC16C5X
ADDWF Add W and f
Syntax: [ label ] ADDWF f,d
Operands: 0  f  31
d 
Operation: (W) + (f)  (dest)
Status Affected: C, DC, Z
Encoding: 0001 11df ffff
Description: Add the contents of the W register
and 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'.
Words: 1
Cycles: 1
Example: ADDWF TEMP_REG, 0
Before Instruction
W =0x17
TEMP_REG = 0xC2
After Instruction
W=0xD9
TEMP_REG = 0xC2
ANDLW AND literal with W
Syntax: [ label ] ANDLW k
Operands: 0  k  255
Operation: (W).AND. (k)  (W)
Status Affected: Z
Encoding: 1110 kkkk kkkk
Description: The contents of the W register are
AND’ed with the eight-bit literal 'k'.
The result is placed in the W regis-
ter.
Words: 1
Cycles: 1
Example: ANDLW H'5F'
Before Instruction
W=0xA3
After Instruction
W=0x03
ANDWF AND W with f
Syntax: [ label ] ANDWF f,d
Operands: 0  f  31
d 
Operation: (W) .AND. (f)  (dest)
Status Affected: Z
Encoding: 0001 01df ffff
Description: The contents of the W register are
AND’ed with register 'f'. If 'd' is 0
the result is stored in the W regis-
ter. If 'd' is '1' the result is stored
back in register 'f'.
Words: 1
Cycles: 1
Example: ANDWF TEMP_REG, 1
Before Instruction
W=0x17
TEMP_REG = 0xC2
After Instruction
W =0x17
TEMP_REG = 0x02

Syntax: [ label ] BCF f,b
Operands: 0  f  31
0  b  7
Operation: 0  (f<b>)
Status Affected: None
Encoding: 0100 bbbf ffff
Description: Bit 'b' in register 'f' is cleared.
Words: 1
Cycles: 1
Example: BCF FLAG_REG, 7
Before Instruction
FLAG_REG = 0xC7
After Instruction
FLAG_REG = 0x47
