RS1 and RS0 determine which Register Bank is active. OV flag is set on overflow. The overflow condition depends on the operation which

PSW (Program Status Word) is of 16 bit. 5. Necessary (for literal value). Question paper with solution the 8051 microcontroller based embedded systems... manishpatel_79.

It contains several status bits that reflect the current state of the CPU. Besides, this register contains Carry bit, Auxiliary Carry, two register bank select bits, Overflow flag, parity bit and user-definable status flag. P - Parity bit. If a number stored in the accumulator is even then this bit will be
