BTFSS
Bit Test f, Skip if Set
Syntax:
[
label] BTFSS f,b
Operands:
0
≤ f ≤ 127
0
≤ b < 7
Operation:
skip if (f<b>) = 1
Status Affected:
None
Description:
If bit ’b’ in register ’f’ is ’0’, then 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 2TCY instruc-
tion.
BTFSC
Bit Test, Skip if Clear
Syntax:
[
label] BTFSC f,b
Operands:
0
≤ f ≤ 127
0
≤ b ≤ 7
Operation:
skip if (f<b>) = 0
Status Affected:
None
Description:
If bit ’b’ in register ’f’ is ’1’, then the next
instruction is executed.
If bit ’b’ in register ’f’ is ’0’, then the next
instruction is discarded, and a NOP is
executed instead, making this a 2TCY
instruction
.
CALL
Call Subroutine
Syntax:
[
label ] CALL k
Operands:
0
≤ k ≤ 2047
Operation:
(PC)+ 1
→ TOS,
k
→ PC<10:0>,
(PCLATH<4:3>)
→ PC<12:11>
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 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.
