Bit Test f, Skip if Set
[ label ] BTFSS f,b

0
skip if (f<b>) = 1
If bit ‘b’ in register ‘f’ is ‘1’, then the
next instruction is skipped.
If bit ‘b’ is ‘1’, then the next instruc-
tion fetched during the current
instruction execution, is discarded
and a NOP is executed instead,
making this a 2-cycle instruction.
Subroutine Call
[ label ] CALL k
0
(PC) + 1
k
(Status<6:5>)
0
Subroutine call. First, return
address (PC + 1) is pushed onto
the stack. The eight-bit immediate
address is loaded into PC bits
<7:0>. The upper bits PC<10:9>
are loaded from STATUS<6:5>,
PC<8> is cleared. CALL is a two-
cycle instruction.
Clear f
[ label ] CLRF
0

The contents of register ‘f’ are
cleared and the Z bit is set.

The CLRWDT instruction resets the
WDT. It also resets the prescaler, if
the prescaler is assigned to the
WDT and not Timer0. Status bits
TO and PD are set.
Complement f
[ label ] COMF
0
d
(f)
The contents of register ‘f’ are
complemented. If ‘d’ is ‘0’, the
result is stored in the W register. If
‘d’ is ‘1’, the result is stored back in
register ‘f’.
