The deep-sleep mode suspends the PS and waits to be woken up. The lowest power deep sleep is supported for wake sources GPI and RTC. Other sleep states are supported for wake sources of USB and Ethernet, with additional power for the wake source. Upon wake, the PS does not have to go through the boot process and the security state of the system is preserved. This reduces the restart time of the system.
The device consumes the lowest power during this mode while still maintaining its boot and security state. The PMU is placed in a sleep or suspend state waiting to be interrupted.
During the deep-sleep mode, the wake signal can be generated either through a GPI input routed from an MIO pin or by an RTC alarm.
