CLRWDT
Clear Watchdog Timer
Syntax:
[
label ] CLRWDT
Operands:
None
Operation:

Description:
CLRWDT
instruction resets the
Watchdog Timer. It also resets the
prescaler of the WDT. Status bits
TO and PD are set.

COMF
Complement f
Syntax:
[
label ] COMF
f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f)
→ (dest)
Status Affected:
Z
Encoding:
00
1001
dfff
ffff
Description:
The contents of register ’f’ are
complemented. If ’d’ is 0, the
result is stored in W. If ’d’ is 1, the
result is stored back in register ’f’.
Words:
1
Cycles:
1
Example

REG1,0
Before Instruction
REG1
=
0x13
After Instruction
REG1
=
0x13
W=
0xEC
DECF
Decrement f
Syntax:
[
label ] DECF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f) - 1
→ (dest)
Status Affected:
Z
Encoding:
00
0011
dfff
ffff
Description:
Decrement 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:

DECFSZ
Decrement f, Skip if 0
Syntax:
[
label ] DECFSZ f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f) - 1
→ (dest);
skip if result = 0
Status Affected:
None
Encoding:
00
1011
dfff
ffff
Description:
The contents of register ’f’ are
decremented. If ’d’ is 0, the result
is placed in the W register. If ’d’ is
1, the result is placed back in reg-
ister ’f’.
If the result is 0, the next instruc-
tion, which is already fetched, is
discarded. A NOP is executed
instead making it a two cycle
instruction.
