Bit Test, Skip if Clear
[label] BTFSC f,b
0
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 2 T
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 instruction
is discarded and a NOP is executed
instead making this a 2T

(PCLATH<4:3>)
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
instruction.
