Re: [lpc2000] LPC2138 RTCX pins when not used for clock?

2005-07-03 by sudip nag

Hi Bill,
LPC2138 RTC pins may be kept unwired (do not connect any thing) and let the registers in default state while you are not using. There is no special consideration for this and thus trivial to mention in datasheet. The RTC register definition is sufficient.

I'm designing a LPC2138 board without an external RTC xtal circuit.  
Any ideas how to handle the RTCX1 & RTCX2 real time clock oscillator 
pins when not used?  The manual doesn't seem to have a recommendation 
for this.
