Example
Bit Test f, Skip if Clear
[ label ] BTFSC f,b
0 ≤ f ≤ 127
0≤b≤7
skip if (f<b>) = 0
None
01 10bb bfff ffff
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 2 cycle
instruction.
