E22 deep sleep mode

Hi; How can I use deep sleep mode in e22? I connected 3v to M0 and M1 pins and I did not get any results, so I did not understand how to do it. For example, I want to use it with esp8266 in deep sleep mode. When the esp wakes up and sends data, the M0 M1 pins of the e22 should be pulled to 0 and when the esp goes to sleep, should I send 3 v to the M0 and M1 pins and put them into sleep mode?
