Bit Test f, Skip if Clear

0
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 two-cycle instruction.
Bit Test f, Skip if Set
[label] BTFSS f,b
0
0
skip if (f<b>) = 1
None
If bit ‘b’ in register ‘f’ is ‘0’, the next
instruction is executed.
If bit ‘b’ is ‘1’, then the next instruc-
tion is discarded and a NOP is
executed instead, making this a
two-cycle instruction.
Call Subroutine

(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.
