BCF

Bit Clear f

Syntax:

[ label ] BCF

f,b

Operands:

 f  127

 b  7

Operation:

 (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 two-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 two-cycle instruc-

tion.

BSF

Bit Set f

Syntax:

[ label ] BSF

f,b

Operands:

 f  127

 b  7

Operation:

 (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:

 f  127

 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:

 f  127

 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.
