CALL
Call Subroutine
Syntax:
[ label ] CALL k
Operands:
0
k 2047
Operation:
(PC)+ 1
TOS,
k
PC<10:0>,
(PCLATH<6:3>)
PC<14:11>
Status Affected:
None
Description:
Call Subroutine. First, return address
(PC + 1) is pushed onto the stack.
The eleven-bit immediate address is
loaded into PC bits <10:0>. The upper
bits of the PC are loaded from
PCLATH. CALL is a two-cycle instruc-
tion.
CALLW
Subroutine Call With W
Syntax:
[ label ] CALLW
Operands:
None
Operation:
(PC) +1
TOS,
(W)
PC<7:0>,
(PCLATH<6:0>)
PC<14:8>
Status Affected:
None
Description:
Subroutine call with W. First, the
return address (PC + 1) is pushed
onto the return stack. Then, the con-
tents of W is loaded into PC<7:0>,
and the contents of PCLATH into
PC<14:8>. CALLW is a two-cycle
instruction.
CLRF
Clear f
Syntax:
[ label ] CLRF
f
Operands:
0
f 127
Operation:
00h
(f)
1 Z
Status Affected:
Z
Description:
The contents of register ‘f’ are cleared
and the Z bit is set.
CLRW
Clear W
Syntax:
[ label ] CLRW
Operands:
None
Operation:
00h
(W)
1 Z
Status Affected:
Z
Description:
W register is cleared. Zero bit (Z) is
set.
CLRWDT
Clear Watchdog Timer
Syntax:
[ label ] CLRWDT
Operands:
None
Operation:
00h
WDT
0 WDT prescaler,
1 TO
1 PD
Status Affected:
TO, PD
Description:
CLRWDT instruction resets the Watch-
dog 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)
(destination)
Status Affected:
Z
Description:
The contents of register ‘f’ are com-
plemented. If ‘d’ is ‘0’, the result is
stored in W. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.
DECF
Decrement f
Syntax:
[ label ] DECF f,d
Operands:
0
f 127
d
[0,1]
Operation:
(f) - 1
(destination)
Status Affected:
Z
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’.
