capacitor and resistor in reset pin perform power up reset.by starting theciruit capacitor is decharge (vc=0)so vcc drop on reset.then capasitor charge and after 5t(t=r*c)vc reach to vcc so voltage drop on reset pin=0 so with starting the circuit uc reset and then go in normal mod.
with 4 7seq you can easily use of timer with 5ms and interrupt.write on first 7seg and wait 5ms-then next... (multiplexing mode)by this method u can connect 6 7seq and displayin without flicking.
