Define the Edge-Triggered Flip-flops?
An edge-triggered flip-flop changes states either at the negative edge (falling edge) or at the positive edge (rising edge) of the clock pulse on the control input. The three basic kinds are introduced here: S-R, J-K and D.
The S-R, J-K and D inputs are called as synchronous inputs because data on these inputs are transferred to the flip-flop's output only on the triggering edge of the clock pulse. On the other hand, the direct set (SET) and clear (CLR) inputs are called as asynchronous inputs as they are inputs that affect the state of the flip-flop independent of the clock. For a synchronous operation to work properly, these asynchronous inputs should both be kept LOW.
I think yes...so if 8259 gives interrupt then it will be serviced instantly but since into pin is left hanging the insr bit will never be set...and so whenever any interrupt occurs
