Carry flag and over flow flag in 8051?

Carry flag is the the bit 7 of the 8 bit PSW register, whenever there is an addition or subtraction process that has a carry on its 7th bit, the carry flag (C/CY) will be set to 1. OV is set to 1 when there is an arithmetic overflow. this applies to signed and unsigned operations.


If the accumulator has C5H from a previous instruction and the carry flag is set then what will be the contents of the accumulator and carry flag after executing the instruction ADI 94H?

If you add 94H to C5H with the ADI instruction, the result in the accumulator will be 59H and the carry flag will be set. It does not matter what value the carry flag had to start with, because you said ADI, instead of ACI. (For ACI, the result would be 5AH with carry set.)


Show the bit positions of various flags in 8085 flag register?

The 8085 microprocessor has 5 flags: 1. Zero flag: The zero flag is set, when the ALU operation results a zero . 2. Carry flag: If an arithmetic operations results in a carry, this flag is set. 3. Parity flag: This flag is set, when an arithmetic or logical operation results in a data, which has even number of 1s. If otherwise, it is reset. 4. Sign flag: After the execution of an arithmetic or logic operations, if D7 bit of the accumulator is 1, it indicates a negative number and this flag is set. If otherwise, it is reset. 5. Auxiliary Carry flag: used for BCD Operations, During the BCD operations, if D3 bit producing the carry then the AC bit set as1, otherwise the bit is 0. 6. Carry Flag: when a carry is generated by digit D7, then the carry flag set as 1, otherwise the bit will be 0.


How many flag registers are there in 8085?

We have only one flag register of 8 bits. Bits description is as follows (Assuming D0=LSB & D7=MSB) D7=Sign Bit. D6= Zero Flag D4= Auxiliary Carry Flag D2 = Parity Flag D0= Carry Flag.


What is jump on carry in 8085?

Jump on Carry is simply a "JUMP" instruction which will transfer the control to some specific location if carry flag is set. For Example: JC 2004H This instruction will take the control to address location 2004H if carry flag is set.


Which flags are checked after instruction JNC and JNZ?

JNC is Jump No-Carry, so the carry flag is checked. JNZ is Jump No-Zero, so the zero flag is checked.
