The device can be placed in Standby mode to reduce power consumption during low activity levels. This first level of power management allows you to maintain the device context for fast resume times. The main characteristics of this mode that distinguish it from Active mode are:
The above conditions result in lower power consumption than Active mode but require the user to save the switched-off power domain context to On-Chip Memory and restore the contexts to resume properly upon wakeup.
Wakeup in Standby mode is achieved using any GPIO. GPIO wakeup is possible by switching the pad to GPIO mode and configuring the corresponding GPIO bank for generating an interrupt to the Device Manager. Note that pads that do not have a GPIO muxmode (for example, USB) cannot cause these wakeups. If additional or other wakeup sources are required, the associated peripheral module clock and interconnect clock domain should remain enabled (this may require the associated PLL to remain locked) and the module must be configured appropriately for wakeup by configuring it to generate an interrupt to the Device Manager.
