Bit Test f, Skip if Set
[ label ] BTFSS f,b
0 ≤ f ≤ 127
0 ≤ b < 7
skip if (f<b>) = 1
None
01
If bit 'b' in register 'f' is '1' then the
next instruction is skipped.
If bit 'b' is '1', then the next
instruction fetched during the
current instruction execution, is
discarded and a NOP is executed
instead, making this a two-cycle
instruction.

Call Subroutine. First, return
address (PC+1) is pushed onto
the stack. The eleven bit
immediate address is loaded
into PC bits <10:0>. The upper
bits of the PC are loaded from
PCLATH. CALL is a two-cycle
instruction.
