CJNE and JB

Operation:	CJNE
Function:	Compare and Jump If Not Equal
Syntax:	CJNE operand1,operand2,reladdr

Instructions	OpCode	Bytes	Flags
CJNE A,#data,reladdr	0xB4	3	C
CJNE A,iram addr,reladdr	0xB5	3	C
CJNE @R0,#data,reladdr	0xB6	3	C
CJNE @R1,#data,reladdr	0xB7	3	C
CJNE R0,#data,reladdr	0xB8	3	C
CJNE R1,#data,reladdr	0xB9	3	C
CJNE R2,#data,reladdr	0xBA	3	C
CJNE R3,#data,reladdr	0xBB	3	C
CJNE R4,#data,reladdr	0xBC	3	C
CJNE R5,#data,reladdr	0xBD	3	C
CJNE R6,#data,reladdr	0xBE	3	C
CJNE R7,#data,reladdr	0xBF	3	C

Description: CJNE compares the value of operand1 and operand2 and branches to the indicated relative address if operand1 and operand2 are not equal. If the two operands are equal program flow continues with the instruction following the CJNE instruction.

The Carry bit (C) is set if operand1 is less than operand2, otherwise it is cleared.

Instruction Set: JB

Operation:	JB
Function:	Jump if Bit Set
Syntax:	JB bit addr, reladdr

Instructions	OpCode	Bytes	Flags
JB bit addr,reladdr	0x20	3	None

Description: JB branches to the address indicated by reladdr if the bit indicated by bit addr is set. If the bit is not set program execution continues with the instruction following the JB instruction.
