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 instruc-
tion fetched during the current
instruction execution is discarded
and a NOP is executed instead,
making this a two-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 instruc-
tion fetched during the current
instruction execution is discarded
and a NOP is executed instead,
making this a two-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)
