Can someone point me to a definitive / application reference for the Watchdog circuit used in the LPC2xxx - )one that is better than the user manual for LPC2292) I recently started trying to use the watchdog in the LPC2292. Knowing no better, I decided to feed the watchdog once every time I went round my event loop. I was careful to disable* interrupts before writing 0xAA and 0x55 to WDFEE...

Hi all, I'm trying to use an LPC2292 in a extremely low power situtation (i.e. the whole board < 0.5mA at 3.3V). So far, I've put the 2292 into Power Down mode (I see the oscillator stop) and the board gets down to about 0.8mA. I've tried things like: - disabling the EMC and making all pins GPIO inputs (0.8mA) - disablin
