PIC16F753/HV753
BTFSS
Bit Test f, Skip if Set
Syntax:
Operands:
Operation:
Status Affected:
Description:
[ label ] BTFSS f,b
0  f  127
0b<7
skip if (f<b>) = 1
None
If bit ‘b’ in register ‘f’ is ‘0’, the next
instruction is executed.
If bit ‘b’ is ‘1’, then the next
instruction is discarded and a NOP
is executed instead, making this a
two-cycle instruction.
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
Watchdog Timer. It also resets the
prescaler of the WDT.
Status bits TO and PD are set.
CALL
Syntax:
Operands:
Operation:
Status Affected:
Description:
Call Subroutine
[ label ] CALL k
0  k  2047
(PC)+ 1 TOS,
k  PC<10:0>,
(PCLATH<4:3>)  PC<12:11>
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 instruction.
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
complemented. If ‘d’ is ‘0’, the
result is stored in W. If ‘d’ is ‘1’,
the result is stored back in
register ‘f’.
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.
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’.
