Hi,

All GPIO pins in lpc4350 default to inputs with pull-up resistors enabled, it means that it can provide a high level to the peripheral connected with it, such as led, vibrator?

I have tried using the Hitex 4350 dev board, found that the GPIO state is maintained when i call PWR_Sleep() function; the GPIO state can't be maintained when PWR_DeepSleep() is callled, is it right? but i need the maintanied GPIO state when LPC4350 is in deep-sleep state, would you like to provide several suggestions?
thanks in advance.

Regards,
David
