hello folk's (excuse me for my english mistakes, please :)

i have a  problem in wakeup from powerdown using RTC.

i set INTWAKE = 0x8002

(i use also EINT1 (p014 -boot) to wakeup, and this is running ok)

i use the 32Khz quartz for RTC and during normal operation RTC
interrupt is running correctly,  but putting in powerdown (PCON = 2)
RTC interrupt 
do not wakeup the processor.

i'm search my mistake , but for now i have not found the solution.

Someone have suggestion idea?

thank's to all.
