Sleep mode dma wake up

[ujwal_kumar_N_L]

Hi community ,
I'm working on the Sleep modes of the NXP LPC55S69 board.
I'm trying to wake up the system using uart2 which is configurated as DMA will the DMA IRQ wake up the device or I need to Configure the Flexcomm as the Interrupt or the DMA irq will work ??
Device used LPC55S69
Sleep mode wake up using flexcomm2
Thank you and regards 
UJWAL

Hello @ujwal_kumar_N_L 

Yes, need enable DMA interrupt before enter sleep mode, then  DMA interrupt will wake up cpu.
