BCF Clear "b" bit of "f"
Syntax BCF f [,b]
Operands f : 00h ~ 3Fh, b : 0 ~ 7
Operation
(f.b) ← 0
Status Affected -
OP-Code 01 000b bbff ffff
Description Bit 'b' in register 'f' is cleared.
Cycle 1
Example BCF FLAG_REG, 7 B : FLAG_REG = 0xC7
A : FLAG_REG = 0x47
BSF Set "b" bit of "f"
Syntax BSF f [,b]
Operands f : 00h ~ 3Fh, b : 0 ~ 7
Operation
(f.b) ← 1
Status Affected -
OP-Code 01 001b bbff ffff
Description Bit 'b' in register 'f' is set.
Cycle 1
Example BSF FLAG_REG, 7 B : FLAG_REG = 0x0A
A : FLAG_REG = 0x8A
BTFSC Test "b" bit of "f", skip if clear(0)
Syntax BTFSC f [,b]
Operands f : 00h ~ 3Fh, b : 0 ~ 7
Operation Skip next instruction if (f.b) = 0
Status Affected -
OP-Code 01 010b bbff ffff
Description If bit 'b' in register 'f' is 1, then the next instruction is executed. If bit 'b' in
register 'f' is 0, then the next instruction is discarded, and a NOP is
executed instead, making this a 2nd cycle instruction.
Cycle 1 or 2
Example LABEL1 BTFSC FLAG, 1
TRUE GOTO SUB1
FALSE ... B : PC = LABEL1
A : if FLAG.1 = 0, PC = FALSE
if FLAG.1 = 1, PC = TRUE
BTFSS Test "b" bit of "f", skip if set(1)
Syntax BTFSS f [,b]
Operands f : 00h ~ 3Fh, b : 0 ~ 7
Operation Skip next instruction if (f.b) = 1
Status Affected -
OP-Code 01 011b bbff ffff
Description If bit 'b' in register 'f' is 0, then the next instruction is executed. If bit 'b' in
register 'f' is 1, then the next instruction is discarded, and a NOP is
executed instead, making this a 2nd cycle instruction.
Cycle 1 or 2
Example LABEL1 BTFSS FLAG, 1
TRUE GOTO SUB1
FALSE ... B : PC = LABEL1
A : if FLAG.1 = 0, PC = TRUE
if FLAG.1 = 1, PC = FALSE
