Hi,

I have been faced with a strange matter that need some help,
i am using a system that uses Lpc4357 with 208 pin LQFP package,
the processor pin number 181 is used as PB_5 and set to LCDVD14
that is used as bit4 for Green color  in LCD defined as RGB 5:6:5.
the pin number 182 is RTCX1 crystal signal used for internal Rtc.
When i use the bit4 of Green color as described above, Rtc goes forward or backward for
example, 50 minutes every day, when I use PB_5 as a normal Gpio, then
the Rtc operates accurately.
Any Help is appreciated.

Best Regards,
