Relative Branch
[ label ] BRA label
[ label ] BRA $+k
-256  label - PC + 1  255
-256  k  255
(PC) + 1 + k  PC
None
Add the signed 9-bit literal ‘k’ to the
PC. Since the PC will have incre-
mented to fetch the next instruction,
the new address will be PC + 1 + k.
This instruction is a two-cycle instruc-
tion. This branch has a limited range.
Bit Clear f
[ label ] BCF
0  f  127
0  b  7
0  (f<b>)
None
Bit ‘b’ in register ‘f’ is cleared.
Relative Branch with W
[ label ] BRW
None
(PC) + (W)  PC
None
Add the contents of W (unsigned) to
the PC. Since the PC will have incre-
mented to fetch the next instruction,
the new address will be PC + 1 + (W).
This instruction is a two-cycle instruc-
tion.
Bit Set f
[ label ] BSF
0  f  127
0  b  7
1  (f<b>)
None
Bit ‘b’ in register ‘f’ is set.

Description:
Bit Test f, Skip if Clear
[ label ] BTFSC f,b
0  f  127
0  b  7
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-cycle instruction.
Bit Test f, Skip if Set
[ label ] BTFSS f,b
0  f  127
0  b < 7
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
2-cycle instruction.
