CALL

Syntax:

Operands:

Operation:

Status Affected:

Description:

Call Subroutine

[ label ] CALL k

0  k  2047

(PC)+ 1 TOS,

k  PC<10:0>,

(PCLATH<6:3>)  PC<14:11>

None

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

Syntax:

Operands:

Operation:

Status Affected:

Description:

Subroutine Call With W

[ label ] CALLW

None

(PC) +1  TOS,

(W)  PC<7:0>,

(PCLATH<6:0>) 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.

CLRF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Clear f

[ label ] CLRF f

0  f  127

00h  (f)

1Z

Z

The contents of register ‘f’ are cleared

and the Z bit is set.

CLRW

Syntax:

Operands:

Operation:

Status Affected:

Description:

Clear W

[ label ] CLRW

None

00h  (W)

1Z

Z

W register is cleared. Zero bit (Z) is

set.

CLRWDT

Syntax:

Operands:

Operation:

Status Affected:

Description:

Clear Watchdog Timer

[ label ] CLRWDT

None

00h  WDT

0  WDT prescaler,

1  TO

1  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.

COMF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Complement f

[ label ] COMF f,d

0  f  127

d  [0,1]

(f)  (destination)

Z

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

Syntax:

Operands:

Operation:

Status Affected:

Description:

Decrement f

[ label ] DECF f,d

0  f  127

d  [0,1]

(f) - 1  (destination)

Z

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’.
