COMF
Complement f
Syntax:
[
label ] COMF
f,d
Operands:
0
f 31
d
[0,1]
Operation:
(f)
(dest)
Status Affected:
Z
Encoding:
0010
01df
ffff
Description:
The contents of register 'f' are
complemented. If 'd' is 0, the result
is stored in the W register. If 'd' is
1, the result is stored back in regis-
ter 'f'.
Words:

REG1,0
Before Instruction
REG1
=

DECF
Decrement f
Syntax:

f 31
d
[0,1]
Operation:
(f) – 1
(dest)
Status Affected:

ffff
Description:
Decrement 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'.

DECFSZ
Decrement f, Skip if 0
Syntax:
[
label ] DECFSZ f,d
Operands:
0
f 31
d
[0,1]
Operation:
(f) – 1
d; skip if result = 0
Status Affected:
None
Encoding:
0010
11df
ffff
Description:
The contents of register 'f' are dec-
remented. If 'd' is 0, the result is
placed in the W register. If 'd' is 1,
the result is placed back in register
'f'.
If the result is 0, the next instruc-
tion, which is already fetched, is
discarded and a NOP is executed
instead making it a two cycle
instruction.

GOTO
Unconditional Branch
Syntax:
[

GOTO k
Operands:
0
k 511
Operation:
k
PC<8:0>;
STATUS<6:5>
PC<10:9>
Status Affected:
None
Encoding:

kkkk
Description:
GOTO
is an unconditional branch.
The 9-bit immediate value is
loaded into PC bits <8:0>. The
upper bits of PC are loaded from
STATUS<6:5>. GOTO is a two cycle
instruction.
Words:

Example:
GOTO THERE
After Instruction
PC =
address
(THERE)
