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 instruction
fetched during the current instruction
execution, is discarded and a NOP is
executed instead, making this a two-
cycle instruction.

None
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 instruc-
tion.
