Operands:

≤ f ≤ 127

≤ b ≤ 7

Operation:

→ (f<b>)

Status Affected:

None

Encoding:

00bb

bfff

Cycles:

Example

BCF

FLAG_REG, 7

Before Instruction

FLAG_REG = 0xC7

After Instruction

FLAG_REG = 0x47

BSF

Bit Set f

Syntax:

[

label ] BSF

f,b

Operands:

≤ f ≤ 127

≤ b ≤ 7

Operation:

→ (f<b>)

Status Affected:

None

Encoding:

01bb

bfff

ffff

Description:

Bit ’b’ in register ’f’ is set.

Words:

Cycles:

Example

BSF

FLAG_REG,

Before Instruction

FLAG_REG = 0x0A

After Instruction

FLAG_REG = 0x8A

BTFSC

Bit Test, Skip if Clear

Syntax:

[

label ] BTFSC f,b

Operands:

≤ f ≤ 127

≤ b ≤ 7

Operation:

skip if (f<b>) = 0

Status Affected:

None

Encoding:

10bb

bfff

ffff

Description:

If bit ’b’ in register ’f’ is ’0’, then the

next instruction is skipped.

If bit ’b’ is ’0’, then the next instruc-

tion fetched during the current

instruction execution is discarded,

and a NOP is executed instead,

making this a 2 cycle instruction.

Words:

Cycles:

1(2)

Example

HERE

FALSE

TRUE

BTFSC

GOTO

FLAG,1

PROCESS_CO

Before Instruction

PC =

address

HERE

After Instruction

if FLAG<1> = 0,

PC =

address TRUE

if FLAG<1>=1,

PC =

address FALSE
