What do I do with the RTCX1 and RTCX2 pins when not using the RTC on the LPC1768 ?

[atkinsd84]

Hi everyone, I'm struggling with how to terminate unused pins and the data sheet doesn't appear to have all the answers.  Can anyone help me with how to terminate pins 16 and 18 on the LPC1768 when not using the RTC.

Hi David,

I would recommend that RTCX1 be grounded since it is an input. RTCX2 is an output, so it can be left open.

Have a great day,
Sol
