I am simulating a power down condition in uVision using LPC2138. The problem is that the RTC (real time clock) is halting when the processor is in the power down mode. The RTC is using an external clock source 38 Khz and should be active. I want to use the RTC to wake up the processor.
Another problem is that the RTC with external clock is not working when the internal power is off (PCONPB.PCRTC = 0). It should, because the power is now coming from pin nr. 49, Vbat.
Any solutions to this?
Thanks, Petter Gran-Janssen
Thank you Reinhard.
Do you know about a workaround? When will version 3.05 be ready?
Do you know if the wakeup from Power down is OK?

Thank you Reinhard. I am facing this problem as well. By the way, is there any solution for me to wake up the processor from power down mode for this version MDK3.05?
Thanks & BR, WL Chan
