Problem with Wakeup from PowerDown Mode

2005-02-21 by gewitter2000

Hi,

I am just testing the PowerDown Feature with the LPC2138. 

The EXTWAKE1 bit is set for wake up the processor after power down.
I can enter PowerDown Mode (PCON|=0x02;) and the complete application
consumes 30mA instead of 70mA. That's ok due to the external
components not sleeping....

But after wake up the problem is that the processor works in slow
motion and doesn't consume the previously needed 70mA. It consumes
only 40mA. The reading of the PCON register is 0x0.
The reading of the PCONP register is 0x001817BE. (same value after
startup)

Any idea? Thank's to all!

Martin
