PLL IC Unknow pin define and Lock Time ?

The Zc(control charge pump) of MB15E03SL of PLL IC , if connect with PS(power saving) of MB15E03SL of PLL IC.

Question 1,
Will it happen return current to Zc pin and cause abnormal consumption current of PLL IC ?

Question 2,
Will it happen Close Loop VCO Lock Time abnormal?
because while measuring Lock Time , it's happened likely charge / discharge condition that range of lock time was 15msec to 25msec.
