BSF
Bit Set f
Syntax:
[
label ] BSF
f,b
Operands:
0
≤ f ≤ 31
0
≤ b ≤ 7
Operation:
1
→ (f<b>)
Status Affected:
None
Encoding:
0101
bbbf
ffff
Description:
Bit ’b’ in register ’f’ is set.
Words:
1
Cycles:
1
Example:
BSF
FLAG_REG,
7
Before Instruction
FLAG_REG = 0x0A
After Instruction
FLAG_REG = 0x8A
BTFSC
Bit Test f, Skip if Clear
Syntax:
[
label ] BTFSC f,b
Operands:
0
≤ f ≤ 31
0
≤ b ≤ 7
Operation:
skip if (f<b>) = 0
Status Affected:
None
Encoding:
0110
bbbf
ffff
Description:
If bit ’b’ in register ’f’ is 0 then the next
instruction is skipped.
If bit ’b’ is 0 then the next instruction
fetched during the current instruction
execution is discarded, and an NOP is
executed instead, making this a 2 cycle
instruction.
Words:
1
Cycles:
1(2)
Example:
HERE
FALSE
TRUE
BTFSC
GOTO
FLAG,1
PROCESS_CODE
Before Instruction
PC
=
address (HERE)
After Instruction
if FLAG<1>=0,
PC
=
address (TRUE);
if FLAG<1>=1,
PC
=
address(FALSE)
BTFSS
Bit Test f, Skip if Set
Syntax:
[
label ] BTFSS f,b
Operands:
0
≤ f ≤ 31
0
≤ b < 7
Operation:
skip if (f<b>) = 1
Status Affected:
None
Encoding:
0111
bbbf
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 an NOP is
executed instead, making this a 2 cycle
instruction.
Words:
1
Cycles:
1(2)
Example:
HERE
BTFSS
FLAG,1
FALSE
GOTO
PROCESS_CODE
TRUE
Before Instruction
PC
=
address (HERE)
After Instruction
If FLAG<1>
=
0,
PC
=
address (FALSE);
if FLAG<1>=1,
PC
=
address (TRUE)
