NRF52832 easyDMA and I2C

Question

the project has a problem with DMA,the detail is:
on the board,NRF52832 and extern chip communication with i2c bus,the chip through a pulse wake up nrf52832,NRF52832 start work,but the wake up frequency of cpu is 200HZ, and cpu work about 2ms once.So cpu power is 4-5mA,how to Reducing power consumption? 
 i think if extern chip can communication with easyDMA and TWIM,but i look up the sdk code.i find
easyDMA work need with cpu,cpu cann't low power. 
 thank you!
