BCF Bit Clear f
Syntax: [ label ] BCF f,b
Operands: 0
f 127
0
b 7
Operation:
0 (f<b>)
Status Affected: None
Description: Bit ‘b’ in register ‘f’ is cleared.
BRA Relative Branch
Syntax: [ label ] BRA label
[
label ] BRA $+k
Operands: -256
label - PC + 1 255
-256
k 255
Operation: (PC) + 1 + k
PC
Status Affected: None
Description: 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 2-cycle instruc-
tion. This branch has a limited range.
BRW Relative Branch with W
Syntax: [ label ] BRW
Operands: None
Operation: (PC) + (W)
PC
Status Affected: None
Description: 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 2-cycle instruc-
tion.
BSF Bit Set f
Syntax: [ label ] BSF f,b
Operands: 0
f 127
0
b 7
Operation:
1 (f<b>)
Status Affected: None
Description: Bit ‘b’ in register ‘f’ is set.
BTFSC Bit Test f, Skip if Clear
Syntax: [ label ] BTFSC f,b
Operands: 0
f 127
0
b 7
Operation: skip if (f<b>) =
0
Status Affected: None
Description: 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.
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
Description: 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.
