BTFSS
Bit Test f, Skip if Set
Syntax:
Operands:
[

0
b < 7
skip if (f<b>) =
1
None
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 two-cycle instruction.

PC<8>
None
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.

TO, PD
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.

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’.
