skip if (f<b>) = 0
None
If bit ’b’ in register ’f’ is ’1’, the next
instruction is executed.
If bit ’b’ in register ’f’ is ’0’, the next
instruction is discarded, and a NOP
is executed instead, making this a

(PCLATH<4:3>)
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.
