Program Counter (PC): A 16-bit register that holds the memory address of the next instruction to be executed.
Sign Flag (S): Set if the result is negative.Zero Flag (Z): Set if the result is zero.Auxiliary Carry Flag (AC): Set if there is a carry from bit D3 to D4.Parity Flag (P): Set if the result has an even number of ones.Carry Flag (CY): Set if there is a carry from the most significant bit. Instruction Set and Programming
In the early days of computing, machines were massive, room-sized, and used vacuum tubes to process information. As technology advanced, the size of computers decreased, and their capabilities increased. The invention of the microprocessor revolutionized the industry, enabling the creation of smaller, faster, and more efficient computers.
