When two numbers multiply, the Overflow (O) and Carry (C) flag bits are affected based on the result of the multiplication. The Overflow flag is set if the result exceeds the maximum representable value for the given data type, indicating a signed overflow. The Carry flag is typically set if there is a carry out from the most significant bit, which occurs in unsigned multiplication when the result exceeds the capacity of the destination register. Thus, both flags indicate potential issues with the result's representation.

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 happens if you drop a flag?
Nothing 'happens'.
How do you represent 300 in 8 bits?
The binary of 300 is 100101100 which are 9 bits therefore the first 8 bits from LSB goes to the register and the carry is generated and carry flag is set to 1.
What is the use of AC Flag in 8085?
The Auxiliary Carry (AC) flag in the 8085 indicates a carry out of the low order 4 bits of an operation, more specifically that the low order 4 bits are greater than 9 (10012). The AC flag can thus be used to facilitate decimal arithmetic.

How is parity flag affected with the or instruction in 8086 microprocessor?
In the 8086 microprocessor, the parity flag (PF) is affected by the OR instruction based on the result of the operation. The parity flag is set if the number of set bits (1s) in the result is even; it is cleared if the number of set bits is odd. Therefore, after executing an OR instruction, the parity flag reflects the parity of the result of the logical OR operation performed on the operands.
What are the status flags in 8085?
In the 8085 microprocessor, the status flags are specific bits in the flag register that indicate the outcome of arithmetic and logical operations. There are five main flags: the Sign Flag (S), Zero Flag (Z), Auxiliary Carry Flag (AC), Parity Flag (P), and Carry Flag (CY). The Sign Flag indicates the sign of the result, the Zero Flag indicates if the result is zero, the Auxiliary Carry Flag is used for BCD operations, the Parity Flag indicates if the number of set bits is even or odd, and the Carry Flag indicates an overflow in arithmetic operations. These flags are essential for decision-making in program execution and control flow.
What happens when branch instruction comes in 8086?
When a branch (or "jump") instruction is executed, the condition codes bits (in the flag register) determine whether or not the Program Counter (PC register) is changed to the Effective Address specified by the instruction; if not, then the PC is unchanged.
What is flag in networking?
in data transmission or processing it is like a sequence of bits used to mark the beginning and end of the frame .
What is parity flag?
The parity flag is a status flag in the CPU's status register that indicates the parity of the result of the last arithmetic or logic operation. It is set to 1 if the number of set bits (1s) in the result is even, and to 0 if the number of set bits is odd. This flag is primarily used for error detection in data transmission and memory storage. In systems that utilize parity checking, the parity flag helps ensure data integrity by signaling whether the data has been altered or corrupted.
Why did they pick that flag for Washington?
they didn't pick the flag a lady knit the flag and every state that joined the union they kept on changing the numbers of stars in the U.S flag.
