Bit Test f, Skip if Clear
[ label ] BTFSC f,b
0 ≤ f ≤ 127

skip if (f<b>) = 0
None
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.
