SUBWF
Subtract W from f
Syntax:
[ label ]
SUBWF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f) - (W)
→ (dest)
Status
Affected:
C, DC, Z
Encoding:
00
0010
dfff
ffff
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'.

Example 1:
SUBWF
REG1, 1
Before Instruction
REG1 = 3
W= 2
C= ?
After Instruction
REG1 = 1
W= 2
C
= 1; result is positive
Z
= DC = 1
Example 2:
Before Instruction
REG1 = 2
W= 2
C= ?
After Instruction
REG1 = 0
W= 2
C
= 1; result is zero
Z
= DC = 1
Example 3:
Before Instruction
REG1 = 1
W= 2
C= ?
After Instruction
REG1 = 0xFF
W= 2
C
= 0; result is negative
Z
= DC = 0
SWAPF
Swap Nibbles in f
Syntax:
[ label ]
SWAPF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f<3:0>)
→ (dest<7:4>),
(f<7:4>)
→ (dest<3:0>)
Status Affected:
None
Encoding:
00
1110
dfff
ffff
Description:
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'.
Words:
1
Cycles:

Example
SWAPF
REG1, 0
Before Instruction
REG1 = 0xA5
After Instruction
REG1 =
0xA5
W
=
0x5A
TRIS
Load TRIS Register
Syntax:
[ label ] TRIS
f
Operands:
5
≤ f ≤ 7
Operation:
(W)
→ TRIS register f;
Status Affected:
None
Encoding:
00
0000
0110
0fff
Description:
The instruction is supported for
code compatibility with the
PIC16C5X products. Since TRIS
registers are readable and
writable, the user can directly
address them.
Words:
1
Cycles:
1
Example
To maintain upward
compatibility with future
PICmicro products, do not
use this instruction.
