Bit Test f, Skip if Set
[ label ] BTFSS f,b
0 ≤ f ≤ 127
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.

(PCLATH<4:3>) → PC<12:11>
None
Call Subroutine. First, return
address (PC+1) is pushed onto
the stack. The eleven bit immedi-
ate address is loaded into PC bits
<10:0>. The upper bits of the PC
are loaded from PCLATH. CALL is
a two-cycle instruction.
