Hi RDGC_member

Please note for Deep power-down mode, All clocks, the core, and all peripherals are powered down. Only the WAKEUP pins are powered. All functional pins are tri-stated in deep power-down mode except for the WAKEUP pin.

Please use WAKEUP pin wake up LPC804 from deep power down mode.

There is power_mode_switch_lpc demo code under MCUXpresso SDK folder, I suggest you referring it for the low power usage.

Thanks
