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’, 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
tion.
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’, then the next
instruction is executed.
If bit ’b’ in register ’f’ is ’0’, then the next
instruction is discarded, and a NOP is
executed instead, making this a 2T
instruction
Call Subroutine
[ label ] CALL k

k
(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.
