BTFSC
Bit Test File, Skip if Clear
Syntax:
BTFSC f, b {,a}
Operands:
0
≤ f ≤ 255
0
≤ b ≤ 7
a
∈ [0,1]
Operation:
skip if (f<b>) = 0
Status Affected:
None
Encoding:
1011
bbba
ffff
Description:
If bit ‘b’ in register ‘f’ is ‘0’, then the next
instruction is skipped. If bit ‘b’ is ‘0’, then
the next instruction fetched during the
current instruction execution is discarded
and a
NOP is executed instead, making
this a two-cycle instruction.
If ‘a’ is ‘0’, the Access Bank is selected. If
‘a’ is ‘1’, the BSR is used to select the
GPR bank (default).
If ‘a’ is ‘0’ and the extended instruction
set is enabled, this instruction operates in
Indexed Literal Offset Addressing
mode whenever f
≤ 95 (5Fh).
Literal Offset Mode” for details.
