Does CH_PD pin do the same as the Deep Sleep command?

SDK function system_deep_sleep puts ESP8266 into Deep Sleep mode. Chip will wake up after reset pulse on the RST pin.

But what is CH_PD pin functionality? Simetimes that pin marked as CH_EN too. When I pull CH_PD low current consumption is reduced to the deep sleep level. But when I release it, does ESP8266 reset? Or maybe it continues to execute code from the point where CH_PD was pulled low?

Yeah, in terms of power consumption it is the same as pulling the CH_PD pin low. It disables the ESP8266. But yeah, it resets its state as well.
