CALL
Syntax:
Operands:
Operation:
Status Affected:
Description:
Call Subroutine
[ label ] CALL k
0 ï£ k ï£ 2047
(PC)+ 1ï® TOS,
k ï® PC<10:0>,
(PCLATH<6:3>) ï® PC<14:11>
None
Call Subroutine. First, return address
(PC + 1) is pushed onto the stack.
The 11-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
Syntax:
Operands:
Operation:
Status Affected:
Description:
Subroutine Call With W
[ label ] CALLW
None
(PC) +1 ï® TOS,
(W) ï® PC<7:0>,
(PCLATH<6:0>) ï®ï PC<14:8>
None
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.

[ label ] CLRWDT
None
00h ï® WDT
0 ï® WDT prescaler,
1 ï® TO
1 ï® PD
TO, PD
CLRWDT instruction resets the Watch-
dog Timer. It also resets the prescaler
of the WDT.
Status bits TO and PD are set.

Syntax:
Operands:
Operation:
Status Affected:
Description:
Complement f
[ label ] COMF f,d
0 ï£ f ï£ 127
d ï [0,1]
(f) ï® (destination)
Z
The contents of register âfâ are com-
plemented. If âdâ is â0â, the result is
stored in W. If âdâ is â1â, the result is
stored back in register âfâ.
DECF
Syntax:
Operands:

Status Affected:
Description:
Decrement f
[ label ] DECF f,d
0 ï£ f ï£ 127
d ï [0,1]
(f) - 1 ï® (destination)
Z
Decrement register âfâ. If âdâ is â0â, the
result is stored in the W
register. If âdâ is â1â, the result is stored
back in register âfâ.
