If bit 'b' in register 'f' is '0' then the next
instruction is executed.
If bit 'b' is '1', then the next instruction is
discarded and a NOP is executed
instead, making this a 2T

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.
