whether can GPIO group interrupt wake up the LPC4350 from Power-Down mode?

I call PWR_PowerDown() function to put LPC4350 into Power-Down mode in Hitex-A4 board, then I issue a GPIO group interrupt, but the system can't be waked up,
from the LPC4350 user manual, I can find "The GPIO group interrupts can wake up the part from sleep, deep-sleep or power-down modes." may anybody provide
the demo code? thanks a lot!

In deep-sleep and power down the core logic and also GPIO are state retained but not active. You have to use the wake up inputs in the RTC domain to wake up from a low power mode.

Waking up from sleep by GPIO should work.
