BTFSS
Bit Test f, Skip if Set
Syntax:
[
label
] BTFSS f,b
0
≤
f
≤
127
0
≤
b < 7
Operands:
Operation:
skip if (f<b>) = 1
Status Affected:
None
Description:
If bit ‘b’ in register ‘f’ = ‘0’, the next
instruction is executed.
If bit ‘b’ = ‘1’, then the next instruc-
tion is discarded and a
NOP
is
executed instead, making this a 2
T
CY
instruction.
BTFSC
Bit Test, Skip if Clear
Syntax:
[
label
] BTFSC f,b
0
≤
f
≤
127
0
≤
b
≤
7
Operands:
Operation:
skip if (f<b>) = 0
Status Affected:
None
Description:
If bit ‘b’ in register ‘f’ = ‘1’, the next
instruction is executed.
If bit ‘b’, in register ‘f’, = ‘0’, the
next instruction is discarded, and
a
NOP
is executed instead, making
this a 2 T
CY
instruction.
CALL
Call Subroutine
Syntax:
[
label
] CALL k
0
≤
k
≤
2047
(PC) + 1
→
TOS,
k
→
PC<10:0>,
(PCLATH<4:3>)
→
PC<12:11>
Operands:
Operation:
Status Affected:
None
Description:
Call subroutine. First, return
address (PC+1) is pushed onto
the stack. The eleven-bit immedi-
ate address is loaded into PC bits
<10:0>. The upper bits of the PC
are loaded from PCLATH.
CALL
is
a two-cycle instruction.
CLRF
Clear f
Syntax:
[
label
] CLRF f
0
≤
f
≤
127
00h
→
(f)
1
→
Z
Operands:
Operation:
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
00h
→
(W)
1
→
Z
Operation:
Status Affected:
Z
Description:
W register is cleared. Zero bit (Z)
is set.
CLRWDT
Clear Watchdog Timer
Syntax:
[
label
] CLRWDT
Operands:
None
00h
→
WDT
0
→
WDT prescaler,
1
→
TO
1
→
PD
Operation:
Status Affected:
TO, PD
Description:
CLRWDT
instruction resets the
Watchdog Timer. It also resets the
prescaler of the WDT. Status bits
TO and PD are set.
