Bit Test f, Skip if Set

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 imme-
diate address is loaded into PC
bits <10:0>. The upper bits of
the PC are loaded from
PCLATH. CALL is a two-cycle
instruction.
