BTFSS
Bit Test f, Skip if Set
Syntax:
[
label
] BTFSS f,b
Operands:
0
≤
f
≤
127
0
≤
b < 7
Operation:
skip if (f<b>) = 1
Status Affected:
None
Encoding:

11bb
bfff
ffff
Description:
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.

Description:
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
