Dear all,
  I am using RTC in LPC1778 controller. I have connected 32.768KHz crystal via 22pf capacitors as given in the controller datasheet. In some of my cards, RTC oscillation taking 10 to 15mintues to start oscillations. In some of my cards it is working fine. Is it controller issue or any?
  Can u help to solve this issue.
